Elden Ring: From Scary Soulslike to First-Person Mod.

Vermis is an artbook series exploring the world of a terrifying horror game that doesn't actually exist, inspired by old dungeon-crawler games and FromSoftware's worldbuilding. Despite being a niche concept, it has found crossover appeal and is already on its third print run. The artbook describes character classes, monsters, and creatures, and is being used by Dungeons and Dragons fans for inspiration in their own campaigns.
