A basilisk was an immortal that resembled a seven-foot-tall, elegantly-featured lizard with slit-pupil eyes that faced forward like a predator's, varied gray and white skin, and silver talons. It walked upright on its hind feet and often used one hand to carry its tail off the ground. Basilisks learned new languages very quickly and loved gossip. The basilisk's main hobby was traveling.
Basilisks possessed a unique array of magical skills, including a sort of screech that could turn any being within range to stone. Basilisks were themselves stone-eaters, though Tkaa once expressed a preference for rare or aged stone, rather than that created by his own magic.
