You can never have too many monsters! This book contains 46 new monsters found in the Inner Sea region—all invented specifically for the Pathfinder Campaign Setting! Some, like the gearsmen of Numeria or the moth-like star monarchs who serve the goddess of dreams, have been mentioned many times in Pathfinder Campaign Setting books, but others like the alien vespergaunt or Rahadoum's desert-dwelling whirlmaws have only been obliquely illustrated or mentioned before. And some make their appearance for the first time in print after debuting in Paizo's office campaigns (like the mysterious and ancient veiled masters, or the disturbingly alluring fungus queen). With monsters ranging in challenge rating from 1/2 (such as the capering monkey goblin or the enigmatic lashuntas) all the way up to beyond CR 20 (including two immense spawn of Rovagug and three powerful outsiders with sinister agendas for the Inner Sea region, like the exiled infernal duke Lorthact), along with three new monstrous templates (the exotic mind-draining vetala vampire, the blighted fey of Fangwood, and the twisted mutants of the Mana Wastes), the Inner Sea Bestiary is set to add a host of new favorite beasties to any Pathfinder game!
