 Reeah is an evil and giant snake monster that was bred by the Ra-Kacharz on orders from the Shadow Lord to guard the opal that was placed on the crown which sits on Reeah's head.In the anime, Reeah was hydra-like with two additional eyeless heads that function as his limbs.Reeah originally dwelled in the sewers and cellars of Hira, feeding on the rats while growing to his current size as his food source became so numerous that they overran the city and so the people were forced to leave and founded Noradz elsewhere, leaving Reeah to claim the renamed City of Rats as his domain, with an abundant food supply.
