The Mamluks

Mozenrath's Mamluks are shambling, undead zombies. Mamluks often carry scimitars, and are usually attired in rags. Since he can always create more, Mozenrath has an endless supply of Mamluks. He even turned his old master, Destane, into a Mamluk (after stealing his power and his kingdom, of course). Though they are stupid and fall apart easily, they are very strong, and are relentless.

The Citadel The Lost City of the Sun	Black Sand The Hunted

Frank Welker probably gave the Mamluks their undead moans, but I'm not sure...
