Dînadan on Deviantart this proposal to share, which makes a lot of sense given Nevaz Derom's proximity to Avras:

Not up on 9th Age lore, but does there exist the same animosity between dwarves and ratmen as between WH Dwarfs and Skaven? Maybe they could even be ratman pelts?
While Mercenary Armies on T9A had this to share. Seeker nest like Karak Kadrin ahoy?

At the time of their construction, the gates were able to open mechanically and were heavily armed. Despite the extraordinary structural defense, the gates fell against the astuteness of the Rat Legions. The gates serve as a wall and fortress, no longer moving, and as a stronghold of the Path of Revenge, the famous crested dwarf brotherhood."

. it fits with a Dacian style, defeated by romans / rats legions.
for me is a good starting point. we should try to find a name and a good bg for characters. Decebalo but dwarvish version.

the Path of Revenge is a project to make an army out of Fireslayers/Seekers

I’ve always considered that axes are such a deep part of dwarf psyche that they transgress cultural stylings.
