Victor Corvinus never wanted to be a hero. He just wanted to finish his psychology thesis and pay off his student loans. Instead, a distant relative left him a "fixer-upper" estate on the edge of reality: Blackwood Manor. It’s a Victorian castle connecting twelve different dimensions, and it comes with a fifty-million-dollar debt, a leaky roof, and tenants who refuse to move out. But these aren't your average squatters. In the basement, Fenrir, the Norse Wolf God destined to devour the sun, is hiding under a paper bag, paralyzed by crippling social anxiety. The Vampire Queen, Carmilla, hasn't drunk blood in centuries because it’s "unsanitary," preferring to patrol the halls with an army of Roombas to satisfy her severe OCD. Even the butler, Yggdrasil, is a World Tree with advanced dementia who occasionally teleports the guest bathroom into an active volcano. Victor has no magic sword, no fireball spells, and absolutely no combat experience. What he does have is a clipboard, a comfortable couch, and a PhD in talking people down from the ledge. In a world where the System usually rewards slaughter with XP, Victor discovers a unique path to survival: he doesn't get paid to kill monsters. He gets paid to *cure* them. Now, with the Gods of Chaos knocking at the door and the Church branding him a heretic, Victor must turn this asylum into a functioning clinic before the Red Moon drives the entire multiverse insane. The interest on his debt is compounding every second, and the World Eater needs to be convinced that the mailman isn't an assassin. Welcome to Blackwood Manor. The Doctor is IN.
