Case history

Rat King lore

The cryptid ruler of the New York Warrens, The Rat King towers over his subjects in size, strength, and ambition. No longer content with hiding underground, the king has revealed his bold vision for a future where he and his subjects can walk the surface without fear of the pest control vans that roam the streets of New York (or as the rats call them: human death squads)

Step 1: Take control of Long Island

Step 2: Declare Long Island as the new sovereign nation of Ratannia

Step 3: Execute every human that refuses to leave this new rat utopia

But air tight as this plan is, the king of rats didn't want to take chances: and so he's decided to summon the patron to help hedge his bets.
