Lacedons were an aquatic subtype of ghoul. They were relatively common, but primarily found in the seas. Like the typical ghoul, lacedons are monstrous, undead humans who reek of carrion. The lacedon have pale skin and long tongues.
A ghoul is said to be created on the death of a man or woman who savored the taste of flesh. They not only eat the dead, but also prey on the unwary living. Likewise, a ghast is supposedly made while someone dies during the act of cannibalism. Ghouls can paralyze their victims with a touch, though elves are immune. Aside from the standard variety, a number of other forms of ghoul exist.
