Súton

súton m (Cyrillic spelling су́тон) dusk, twilight

The Hero and his party failed to defeat the ancient evil the gods had chosen them to eradicate. They all perished, like all the others who had been sent before them, leaving one survivor behind, a snarky raven-haired boy with attachment issues and an obsession for all things shiny.

But Theo is pissed at the gods for allowing his brother and many other teenagers to die because of their own incompetence and refusal to pick someone with an actual chance or experience. He is determined to make his point loud and clear to the arrogant pricks, and if that includes killing one or more of them, then so be it.

Armed with his trusty battle-axe and a clingy emotional support teen who suffers from an utter lack of common sense and self-preservation and is currently undergoing a dark and edgy character arc, the retired warrior goes on a quest to find something that could help him kill the gods.
Will he succeed in his goal? And if so, then what?

OR
Theo goes on a quest for revenge and Silas casually pops up along the road and refuses to leave him alone because he is also mad that the gods killed his friends and he didn't so now he can't be with them in the Endless Palaces of Rest to tell them "I told you so". And he uses every opportunity to expose himself as a Niffler in a human body, much to the warrior's despair.
