Battle for the Ironseat Ridge

Military action

A battle between Corellon the Archeart and Gruumsh the Ruiner was held at a then-unnamed hill along the Ironseat Ridge. According to various myths, when Corellon pierced Gruumsh's eye, the Ruiner's blood rained down and mutated the elven Horselords of Laphithas who rode into battle to aid Corellon. Some were fused with their horses and became the first centaurs, while others were transformed into the first orcs.
