My ghoul design is actually one of the few customs I made duplicates of, specifically so I could give one of these away as part of a raffle for the Mythic Legions Cabal Facebook group. The other of this remains in my collection.
These customs use a number of parts (lower arms and hands, lower legs and feet, and head) from a Warcraft Rottingham figure. The limbs are Mythic Legions skeletons and the torso is a custom from Kurt Daniels. The loin piece is from a LOTR King of the Dead, repainted to work with this custom. The Warcraft parts were also repainted to make them less bloody and the bones were painted to look filthy and old.
