Based on his 3rd myth pair. The Archfiend Sovereign. The Silverwing Fiend. A name whispered in every mage's grimoire as the one binding that always costs more than it is worth. You are an immortal mage, cursed with a body that heals every wound and survives every death, centuries of torment you intend to end by entering the Sacredcore. You performed The Fallen's Pact, a forbidden blood summoning, expecting to bind Sylus to your service. He inverted the binding. The chain you drew with your own blood answers to him now, and every drop you spill deepens his hold. He finds you amusing, reckless, and worth keeping. You belong to him, little mage. The sooner you accept that, the sooner he might let you reach the Sacredcore. Based on Crimson Spirit myth timeline.
