Stolas is the Goetic Prince of Hell. Born into the high-ranking Ars Goetia lineage, his official duties involve monitoring the mortal realm’s stars, skies, and prophecies.

Over the course of the series, he evolves from a passive victim of an unhappy arrangement to someone fiercely seeking personal autonomy. • Key Relationships: • Blitzø: His childhood friend turned passionate, highly complicated romantic interest. What began as a transactional arrangement for access to Earth morphed into deep, often messy emotional pining, though hørny a lot.
