Thus far I have the framework for Pagans, Hammerites, and Keepers.
The Hammerites would basically be a male version of the Sisters of Sigmar, no sense in breaking what isn't broken. Just a few tweaks, a bit more technology oriented then the Sisters but otherwise pretty much the same flavor. Heroes would be a Forger, 0-2 Senior Brothers, 0-2 Acolytes, and an Inspector. Hammerite Brothers and Initiates would be the bulk of the henchmen. Obviously they would worship Sigmar as the Builder and Lord of the Hammer, and choose Spells same as a warrior priest or Sigmarite Matriarch. The Inspector would be similar in combat capability to an Augur, and would give bonus rolls in exploration due to the nature of his job.
The Keepers would have a master, 0-2 Enforcers, 0-2 Acolytes, and an Interpreter option for heroes. Keepers and Guards as Henchmen options. I see them as an interesting warband with only the Enforcers being really combat oriented, the rest being more spellcaster or non combatant types. Still working on the specifics of it though, not much is set in stone.
The Pagans are up in the air for me, I want to include shamans and beasties (dryad type things), but otherwise I am not quite sure where to go. Lots of potential with them though.
I want to make a Garrett Dramatis Personae, and create a couple of scenarios around the pagans, mechanists, and the Hag, and have some ideas for those as well.
Sucks about the hearing, definitely need it to play the game.
