From publisher blurb:
Each release for Crawthorne's Catalog of Creatures for the Pathfinder RPG presents a single, new creature for your Pathfinder RPG game, as presented by the famous and retired monster hunter and adventurer, Lord Crawthorne. Each release presents game stats for the new creature, as well as three adventure ideas to help insert them into your game.
The Storm Serpent is so named because it so enjoys sewing chaos with its ability to create massive, long-lasting storms that cause havoc for anyone caught in them. They are also deadly combatants capable of obscuring vision and unleashing a blast of concussive air from their fanged mouths.
