The guide details the company’s history, principles, organization, recruitment, hiring practices, and notable and generic NPCs. It also introduces fourteen mounted-combat feats, including Mount Specialization, Riding Mastery, Great Trample, and Deathly Charge, along with the fierce firedrake creature.
