Warning: Spoilers/plot details follow.

Siris (Loudspeaker icon blue.pngSIGH RISS), previously known as Ausar (Loudspeaker icon blue.pngOW sar), is the protagonist of the Infinity Blade series. His name is not known to players in the first Infinity Blade game; it is revealed in the novel Infinity Blade: Awakening as well as in Infinity Blade II and Infinity Blade III.


Ausar the Vile

Siri was once Ausar the Vile, a ruthless Deathless warlord who was feared by his friends and enemies alike. He became an ally of the Worker of Secrets only to betray him later and steal the Infinity Blade, locking him in the Vault of Tears. He is later, however, slain by Raidriar on the Plains of Koroth. It is heavy implied that his golem TEL used the Redeemer to give him rebirth in the form of the Sacrifice, Siris.

Infinity Blade: Awakening

Siris is the Sacrifice, a boy raised to journey to the God King's castle and fight him. The Sacrifice wasn't expected to win, it was just a practice to show the God King that the world didn't belong to him. Unexpectedly, he manages to defeat the God King and takes the Infinity Blade for himself. He comes home to his village, Drem's Maw, and expects to be praised for his actions. Instead, he is banished from the village because the people feared that more Deathless would come and make their lives more difficult while searching for the Infinity Blade. From there, Siris sets off to the God King's citadel once more. Upon reaching the castle, he meets Isa in a complicated situation, who helps him find the Worker of Secrets, creator of the Infinity Blade. At the time, he was a seemingly valid person to find help in ridding the world of the Deathless. Siris then journeys away from the God King's palace to find more information on where to find the Worker.

Rebirth of Siris

Infinity Blade II

Siris' actual appearance is first revealed at the entrance to Saydhi's Estate. Isa informs him that Saydhi is a Deathless information dealer. She tells him that if Siris can defeat her champions, Saydhi will answer a question for him. After defeating the Titans, Saydhi compliments Siris' legendary skill with the Aegis forms. She offers him a chance to become her new champion, but Siris refuses, demanding the location of the Worker. Saydhi is shocked, asking which immortal's child he is. Siris demands she answer the question, and Saydhi upholds her end of the bargain, telling Siris that the Worker can be found in the place known as Saranthia, in the Vault of Tears. Fearing that Siris will release the Worker, Saydhi attacks Siris, but is swiftly defeated and killed by the Infinity Blade, ending her immortal life.

Behind her throne, Siris sees a small pillar with a slot shaped like the Infinity Blade, similar to the one he found in the dungeons in the God King's castle. He inserts the weapon, thinking it would open a secret area, and the Blade disappears. The God King appears behind Siris and, revealing that it was a trap, wields the Infinity Blade. Siris is surprised the God King is still alive, and demands he fight him. The God King denies, and claims Siris surprised him last time. He brings up the Infinity Blade into an attack stance and is about to kill Siris, but Isa shoots Siris in the forehead with her crossbow, allowing him to be reborn. Siris wakes up, amazed that he is still alive. He realizes that he is a Deathless, and that TEL had been stopping him from being reborn, instead forcing him to be born as a new human every time he was sacrificed to the God King.

Thus begins Siris's quest to free the Worker of Secrets. He arrives at Saranthia, claiming that he will free the Worker. On the top of the tower, Siris encounters Thane, a Deathless who has been tasked with guarding the Worker. Thane regards Siris as a mortal, stating "This place holds nothing but death for one such as you." After Thane is defeated, Siris steps toward the Blood Seal in the center of the plaza. Thane once again warns Siris that activating the seal will cost Siris his life. Siris persists, stating that Thane is mistaken and that he is, in fact immortal. He jams his fist into the Seal, thus unlocking all rooms in the tower and causing his body to burn out.

At each Seal Siris finds, there is a Blood Sentinel guarding it. The first Sentinel Siris encounters is a Devoted Archivist, studying a large obelisk written in Pangean. The Archivist tells Siris the history of Saranthia, saying it was home to the most vile evil ever to befall the world, and that the Seals must never be broken, for this evil must never be allowed to return. Believing Siris to be a mortal, he attacks him, claiming he does so with regret. He later realizes that Siris is, in fact, Ausar. After the Archivist is defeated, he claims that Siris will fail in his quest to free the Worker, then collapses and dies. Siris is unbowed, and activates the Seal.

The second Blood Sentinel is found in a cave underneath Saranthia and seems to be, at first, a Plated Guard. He is immediately crushed by and replaced with a Stone Demon, the actual Sentinel. The demon is bested, and the second Seal is activated.

The third Blood Sentinel is an Exo-Pilot found in a garage. He refuses to surrender and takes control of the MX-Goliath. Even with the mech, he is no match for Siris. The third and final Blood Seal is activated, thus opening the Vault and opening the path to the Worker.

When Siris returns to the Tower, he is surprised to find Thane guarding the entrance to the Worker's prison, claiming he saw Thane die. Thane retorts, saying he saw Siris do the same, confirming that he is a Deathless. He tells Siris he is a fool for believing he can betray the Deathless and harvest the Worker's secrets for himself. Thane challenges Siris a second time, and is defeated again and knocked off the Tower. Siris activates the Blood Seal again, but this time, it causes the floor to descend into the Vault of Tears. Once inside, Siris sees a strange hooded figure sitting quietly in a stone chair. He approaches the man, but is blocked off by Thane who jumps into the prison. Thane is bested a third time, this time being knocked backwards toward the hooded figure. The figure activates something on Thane's back, causing him to collapse to the ground, his body being bent and contorted in a harsh blue glow. This figure is the Worker of Secrets, and had just previously destabilized Thane's Quantum Identity Pattern, killing him permanently. The Worker is surprised that his old friend Ausar has at last come to free him, but is regretful to state that he cannot leave until Raidriar, the God King, releases him. He tasks Siris with bringing Raidriar back alive. Siris is apprehensive, fearing that he won't be able to defeat Raidriar a second time. The Worker reassures him, claiming there is no other way.

Siris arrives back at Saydhi's Estate, and issues a challenge to Raidriar. Raidriar arrives, sending his minions as fodder to weaken Siris. After his henchmen are defeated, Raidriar himself faces Siris, claiming he will finally taste true death. Raidriar fights ferociously, but is ultimately defeated. Siris takes the Infinity Blade back, poising it to strike. Raidriar states that killing him won't end Siris' conflict with the Deathless. Instead of killing him, Siris strikes Raidriar over the head with the Blade's pommel.

Siris returns to the Worker's tomb with the unconscious Raidriar and drops him off, ready to free the Worker. The Worker congratulates Siris on his victory, and tells Siris that together they will both re-shape their world. Siris inserts the Infinity Blade into the seal on the floor. Once the worker grabs onto the Blade, Siris is propelled backwards by a burst of energy released from the blade. The Worker takes up the blade, and, his tone turning suddenly sinister, tells Siris that in order for him to escape, Siris must take the Worker's place in the vault. The Worker thanks Siris for eliminating many of his rivals, and plots to rule over the Deathless with the Infinity Blade. The Worker ascends as he tells Siris that it is fitting he stay locked in here, because Siris imprisoned the Worker to begin with. Siris' story ends with him and Raidriar locked in the Vault of Tears.

When all seems lost, a hooded figure approaches with a staff on her back. It is revealed to be Isa and she goes into combat position. She is most likely to help free Siris.

Vault of Tears

In the first single-player expansion pack for Infinity Blade II, Siris finds himself delver deeper into the secrets of Saranthia, and uncovers hidden secrets about his past life. His quest starts when he finds an old map that depicts a figure wearing a set of black armor raising a twisted sword in front of the Shrine. He feels the armor is linked to the Shrine, and sets out to obtain it. He finds the Vile Blade stuck in a tree stump, which turns out to be a Bog Giant that turns into a Moss Golem once it's defeated, the Vile Shield housed in a tomb and guarded by the Dark Fiend, and the Vile Armor in a tree guarded by Gargap. The Vile Helm is obtained from a treasure map depicting a king possibly sentencing a woman.

Once the full set is obtained, Siris travels to the Shrine to complete the map. Once there, the coffin rises from the ground to grant Siris entrance into the tomb. However, TEL appears, and warns Siris that he must not enter the tomb, for only misery awaits below. From here, the player can choose to enter the tomb, or heed TEL's warning and leave. If the player chooses to leave, Siris will exit like normal. If Siris does enter the tomb, he will find a statue of his old self wearing the Vile Armor embracing a woman with her hand stretched in front of her, and a ring levitating above the woman's palm. Tapping on the ring will prompt Siris to investigate. Siris walks around the statue, listening to a past memory of the woman confessing her love to Ausar. As he reaches the back of the statue, he sees a knife hidden behind Ausar's back, and the memory turns remorseful. The woman tells Ausar he's become a tyrant, and that he's out of control, followed by the woman's dying screams. Siris turns away in sorrow, unable to face what his old self has done. TEL apologizes, saying that these memories were supposed to stay hidden forever. The ring slowly levitates down from the woman's palm, and Siris grips it tightly, with apparent remorse. Her confession of her love is repeated as the camera pans out.

Infinity Blade: Redemption

Siris and Isa on the IB:R cover

Infinity Blade: Redemption starts with Siris and Raidriar locked in the Vault of Tears. Inside the vault, Siris wakes up and is quickly attacked by Raidriar. During their fight Raidriar bests him, and blinds him by damaging his eyes. Raidrair then tells him that since they are both locked inside the Vault, their QIP cannot escape to a new body if they are killed, so their QIP will stay in their bodies and heal them from their deaths.

After a while Siris is healed from the injuries Raidriar inflicted, but feels that Ausar the Vile is taking over him, so he quickly attacks Raidriar and defeats him. The two continue their fight where Raidriar and Siris killed each other more than a thousand times.

After two years Isa opens the Vault and descends to save Siris. Raidriar takes this opportunity and kills himself, and this time his QIP escapes through the opening of the Vault. Siris on the other hand is carried by Isa to a secret hideout.

On their journey Isa tells Siris that she has been spreading stories about him, a deathless who is fighting the deathless to free the mortals and has built for him a rebel army to command and fight the deathless.  Siris and Raidriar later team up to defeat the Worker of Secrets.


Infinity Blade III

Siris reappears in Infinity Blade III as one of the main playable characters alongside Isa.

After Raidriar is killed by the Worker of Secrets, Siris goes to Raidriar's stronghold in Larioth, as Raidriar stole the Worker of Secrets' datapod and sent it there in one last act of defiance before he is killed by the Worker. Act I with Siris takes place as he fights his way into Raidriar's room and fights a Soulless Raidriar. The Soulless Raidriar is wielding The Infinity Cleaver, a heavy version of the Infinity Blade. Siris asks him where he got it from and why there is this new Infinity Blade, but the Soulless incinerates himself to protect the Worker's secrets. Siris returns and shows it to Isa, who says she has seen something similar in the Stockpile when she was looking for Siris. She goes there to find a chamber that have slots (similar to the one in the Dark Citadel) for different types of Infinity weapons other than the classic sword. She returns to Siris and they begin collecting all the Infinity weapons.

In Act III, Siris goes to a fighting pit owned by Therin, a Deathless aligned with the Worker who supposedly has an Infinity Weapon. Meanwhile Isa goes to free an old friend of Siris and master blacksmith Jensen. Siris defeats Therin and brings back the Infinity Spear while Isa brings back Jensen. Isa and Siris talk and Isa realizes he is trying to find the Redeemer, the weapon that caused Ausar to be reborn into Siris. She, fearing he intends to use it on himself, gets very angry and feelings are tense afterwards.

In Act IV, Siris goes to the Vault of Tears to retreive the Redeemer while Isa goes to The House of Kor to defeat Lelindre, who has the Infinity Daggers. Siris fights Melek in front of the obelisk from Infinity Blade II. Melek tries to convince Siris to join the Worker, saying he can be restored to his former glory. Siris angrily replies back, refusing and then goes on to fight and then defeats Melek. TEL then activates a rune on the obelisk causing a smaller obelisk with the Redeemer resting on top to appear.

In the final act, Siris and Isa go to the Worker's hideout, The Ark, in an attempt to stop him. When Siris finally fights his way to the Worker a second Soulless Raidriar appears and challenges him. Isa, however, shoots the Soulless with her crossbow and tells Siris to go after the Worker while she defeats the Soulless. After a long battle Siris is disarmed, but uses a similar maneuver to the one he used on Raidriar in Infinity Blade I and impales the Worker with his own Infinity Blade. The Worker laughs, stating how he would never create something that could destroy him, until Siris puts the Redeemer into the hilt of the Infinity Blade, causing the Worker to be reborn as a child. Siris and Isa embrace as they are consumed by the flames produced by the Ark, later rebirthing at the Hideout. They then raise the "Toddler of Secrets" as their own child.

Soul Hunter

In the first content pack, Siris/Isa goes to challenge the Deathless Bloodmage Oslim who has been sent by Galath to kill them.

Ausar Rising

In the second content pack, Isa goes to the Plains of Koroth to find out information about the Worker's plans from a cult dedicated to the revival of Ausar the Vile. After slaying Zuorsara, Soulless Ausar awakens and breaks her neck using the Vile Mace. Isa then informs Siris of what happened. Isa goes to Siris's home, Drem's Maw, to clean up the mess Ausar made while Siris goes to defeat Ausar in the Dark Citadel. Ausar and Siris duel until Siris finally defeats Ausar, disarming him. Ausar says how he has memories and thoughts the Worker knows nothing about and how they will be lost if Siris kills him. Siris, wanting Ausar to disappear forever, stabs Ausar; however, Ausar pulls himself and Siris down to fall into the dungeon, which kills both of them, with Ausar dying permanently and Siris eventually reborn.



  • The names Ausar and Siris appear to be derived from ancient Egyptian myth. "Ausar" is one of the suspected original Kemetian pronunciations for the god of the underworld. The Hellenic understanding of the name, still used today, was "Osiris". (i.e. Ausar was the old identity of (O)Siris) The Osiris element was confirmed by the Fiction Podcast. Additionally, the end part of Ausar sounds a lot like the first part of Siris, which when put together makes Ausiris.
  • It is possible that Ausar could be the main antagonist of the canceled game Infinity Blade: Dungeons.
  • While Donald and Geremy Mustard have confirmed that Galath is older than Siris/Ausar, whether by five minutes or 5,000 years, they would not say.
