เนื้อเรื่อง

Continuing on from the previous entry after The God King was finally slain. The final sacrifice known as Siris ventures into the domain of another Deathless named Saydhi, with the Infinity Blade in hand, to seek information on where he can find the creator of the blade, the Worker of Secrets, in hopes of gaining his aid in ending the rule of the Deathless. He bests Saydhi's champions and gains his reward, having his question about the Worker's location answered, before she attempts to take the Infinity Blade for herself and is defeated. Siris notices an obelisk with a mould for the Infinity Blade and places it in there only for The God King to reveal it was a trap, tricking Siris into believing it would unlock a secret pathway like the one in his castle. He reclaims the Infinity Blade but Siris is shot in the head by his Companion, Isa, before The God King can execute him using the blade. Siris awakens in a rebirthing chamber and embarks on a journey to Saranthia to reach the Vault of Tears where the Worker of Secrets is imprisoned, swearing to free the Worker with his life.
