Quilboars are creatures that resemble bipedal boars. They posed a problem to the orcs who had settled in perpetual war. The Quilboar of Razorfen Downs, the Razormane tribe, have considered an alliance with the undead Scourge though the current status of their pact in the story is unknown. The other Quilboar tribe, the Bristlebacks, are at war with them. Quilboars have shamanistic societies, and many of them are skilled geomancers and hunters.

Note: In World of Warcraft, there is a sword called X’caliboar used by one of the Razormane leaders, Ragglesnout. This name (on the sword) apparently comes from the legenday sword Excalibur in the tale of King Arthur of Camelot.
