Dracor'ezu are humanoid dragonmen. They are demonic in appearances: they have reptilian features with scaly metallic black skin, possessing demonic amber red reptile eyes, and bat-like wings. 

The Dracor'ezu are the magical creations of some powerful wizard, rumored to be the Urgul - a former apprentice of the Archlich of Paligoth and current master of one of the eight towers of Arvernier. It is believed that the Dracor'ezu were spawned of the same magical process that was used in the creation of Draconian from the distant world of Krynn, with the major exception that the dragon eggs used in the creation were infested with chaos and demonic essence. The first appearances of the Dracor'ezu was during the early periods of the War of the Orb where they mainly in the service of the Witchking. The relationship between Urgul and the Witchking is unclear, as is the reasons behind the creation of the Dracor'ezu. Not many of the Dracor'ezu survived the war and those that did broke away from their former masters. The few that remain on Arven continue to remain a threat as they are in essence, demonspawn.

Dracor'ezu speak Abyssal, Common, Draconic, and other local dialects.
