Well, I felt bad that there wasn't any entries yet so I thought I would put my (big) hat into the ring. I've always loved the Chaos Dwarves and I would love to see them make an appearance in Shadespire. So here is my attempt at putting together a warband - however, it should be noted that it is likely very much unbalanced and needs a lot of work/testing/etc.

The Azgorh Slavetakers
The Azgorh Slavetakers are the remains of a failed exploratory and slave-taking mission of the Legion of Azgorh sent to Shadespire to exploit the chaos inflicted by Nagash's curse. However, when the force found it's way to Shadespire, it found the city embroiled in an endless cycle of conflict and rebirth. The majority of the force simply left, but a small contingent sent to scout the ruins was trapped within and is making the best of the situation by collecting slaves and unlocking the secrets of shadeglass.
