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 the summon the patron to help hedge his bets.
