There are Ogre/troll tribes in WHFB, if my memory serves well.
Ents can be a similar minor faction.
Especially when we have dark elves using corrupt treants. It might be an interesting reaction from the Ents to meet them.

Considering the Dark Elves will likely be one of the first enemies the Counties muster against....

I believe the relevant quote is:
