Dominating a portion of the shadowlands? Absolutely! Though that doesn't necessarily have to mean they're native to it!
I dunno about that. Geists don't exactly look a lot like humans, now do they? And the Drust look an awful lot like their (presumably) Undead forms are mutated in some manner.
Why do I even bother to post on this damned site?
These ones? I noticed the Witches in there seem to be opening up Death Magic portals, so these do seem like they're from the other side.

They could have been there so long that they're more Death spirit than human. I mean, I doubt there's anything truly native to the Shadowlands. The Shadowlands appeared alongside mortal life, so everything there likely derives from someone's departed essence. Bwonsamdi might just be some gestalt mishmash of Proto-Troll soul essence that merged together.
Well, they're just referred to as "Fiends" ingame. But the reference to them as Drust Realm monsters has me curious. Especially since they seem to be summoned up from what almost looks to be liquid pools of Death magic. Witches calling up otherwordly forces is cool.
Also, it makes me hope that Horde quests in Drustvar will be under the authority of Bwonsamdi's very own Priesthood or the God himself. I'd love to see rivalry between Death Gods, trying to poach the souls from others.
Good. I'm pretty sure they're meant to be a different sort of thing. Pigman is grotesque butchery. This is "otherwordly thing".
Well, I was trying to come up with a reason why the Horde would want to clean up the Alliance's problems in Drustvar. A reason that was proper Horde-like. Since the Horde tends to do more of the bargaining with spirits thing, and has Bwonsamdi on their side, that just seems like the natural reason for them to want to take out Gorak Tul and his forces. You eliminate him, conduct some rituals to link everything to Bwonsamdi's realm, and you've got all the reason the Horde needs to be there. Feeding our own Death God, rather than clearing up the Alliance Death God problem out of the goodness of our hearts.
