Ghul

Ghuls ("ghouls"): creatures of Neddra, also known as Ghola, Khols, Guula, Ghulka, Corpse-foe, etc. Appear as pallid, human-like (male) corpses, though there are presumably female Ghulka. Ghuls are considered nearly un-killable save by decapitation, wood through the heart, dismemberment, silver (or starsilver rare), "special" weapons, and "magic." They ride Helsteeds and seem to prefer barbed spears and tulwars (a type of saber) as weapons. They act as leaders of lesser Foul Folk and as independent or auxiliary cavalry units. They are much-feared but are not so invulnerable as they first appear.
