That makes a lot of sense, especially in comparison to what we saw in Karak Vlag.
So, first of all, given these clues:
- Morghur is said to have been 'born' three hundred years ago, but there's stories of beings identical to him stretching back throughout recorded history.
- From your very limited knowledge, Morghur was last seen being pursued by High Elves in Bretonnia shortly before the Great War Against Chaos.
This is absolutely not the Morghur that was in Brettonia, but some other creature, likely made in his image by Karag Dum. The beastmen, on the other hand, are absolutely real.
That, in and of itself, is a dangerous game.
So: mad Speculation:
Karagt through secrets only the Sith new, created Karag-Cor, our asffectionate little friend here, to be their personal slave beastman-god. Likely they are trying to use his influence to warp them straight out of the Chaos wastes and into better regions.
This must have been an old plan: more than old enough Borek knows of it, which is, remember, more than 200 years old. Likely, then, its excution is similarly old.
This is likely a hint of longstanding and increasing corruption.
Despite this, I think that at the moment they are onlyu argaining with chaos, not openly worshipping it. OTOH, their fall will be swift, irretreivable, inevitable, and quick. What do?
Run, probably: they are still certainly wrves which worship the ancestors, so killing them is likely not legal or to be approved of, but we have absolutely much much much much much less than no desire to talk to these people: perhaps the best we can do is let them rot until it is fair to kill them.
IF not that, we may have to destroy a dwarf hold. Pray we do not get Grudged.
