Valda's Spire of Secrets is this wild, dense RPG sourcebook packed with lore, but the 'main character' really depends on how you play it! The book introduces the Spire—a mysterious tower crawling with dangers—and lets you craft your own hero to explore it. My favorite part is the flexibility; you could be a cursed scholar unraveling the Spire's secrets or a rogue hunting for lost relics. The setting practically begs you to invent your protagonist, blending dark fantasy with a pinch of cosmic horror. Every time I flip through it, I imagine a new lead for my campaigns—last week, it was a disgraced knight seeking redemption in the tower's shadows.
What's cool is how the Spire itself feels like a character, shifting and reacting to players. The book nudges you toward creating someone tied to its mysteries, like a detective piecing together a nightmare puzzle. I once ran a game where the 'main character' was a former Spire guardian who'd forgotten their past—slowly realizing they were part of its corruption. The emotional beats hit harder when the protagonist's arc intertwines with the setting's creeping dread.
