Direghoul

"There are few creatures so foul and disgusting as a Direghoul. Actually, that's a lie because there are plenty which are far worse, yet my point still remains. I absolutely bloody hate those vile vermin."
-A military officer underneath the command of the Gilded Imperator

The Direghoul, unlike the Ghoul has more of a green rotten colour to it's frame, accompanied by bigger blackish claws hard as steel and overall greater forms which are more hardened, tough and sinewy. Making them a good deal harder to kill than their ordinary ilk.
This creature comes to be if a living ghoul dies and their corpse is brought back to the fray through the same way a ghoul would be brought back to the waking world. The difference is that the soul is still trapped within a Direghoul, making it an unliving vessel rather than a bunch of choppable bloodbags that rush back to their expiration date if their master is put to stake.
The direghoul is usually used as a skirmisher unit among the cannonfodder ghouls. Their job is to harass, wound and maim as many targets as they can during a battle, while the undead army gets wittled away to dull down enemy forces. Which would open ways for the vampires to strike critical points in their foes defences.
