The Forest Horse Clan is a Deep Forest Clan. They suffer in Oath Breaker when their Mage is killed, and is replaced by Thiazzi, the Oak Mage. When a boar is driven mad by pain in Spirit Walker by one of Tenris's Tokoroth, it is done by using a Forest Horse Clan dart.
Their clan tattoos are leaves tattooed all over the face, oak for the women and holly for the men.
They carry green slate knives, bows and arrows with green slate arrowheads, and visciously barbed leaf-shaped throwing darts, made out of dark wood.
