This is one hot game! Seriously, it has the feel of a full race book from one of the much larger games I play, complete with plot hooks, unique creatures and encounters, and culture. It's great that it can act as a stand alone without feeling like a player is missing anything or in addition to your game, Hotshots. It helps that the Eousi are absolutely intriguing, and I really like how you introduced combat to the 3d6D system.
This is a very stellar addition to the jam!
