From publisher blurb:
Erzsak’s Drake Riders is a mercenary company of warriors-for-hire featuring a small army of foot soldiers and specialists, all acting as support for the company’s shock troops, the firedrake riders. Founded by a discontented ex-soldier named Ludvel Erzsak, the group has evolved from a one-time adventuring band to a grand organization with both might and reputation.
Erzsak's Drake Riders details a drop-in mercenary company for your d20 Fantasy game, complete with history, tenets, organizational structures, ways of hiring, ways of joining, iconic and generic NPCs. It also includes 14 new feats dealing with mounted combat in general—from Mount Specialization to Riding Mastery, from Great Trample to Deathly Charge—and a new creature, the fierce firedrake.
