Is there room for a Dwarven city state? 

I would like to use firearms, as they're quite popular in Dwarven fantasy settings, however I agree that they should be in their infancy and totally inferior to say the Elven longbow. More than likely, my missile troops would rely on crossbows, as Dwarves are quite small fellahs, and would struggle to use anything bigger than a short bow. I'd likely equip the King's guard with rifles, and some of the newer more exquisite formations. I imagine they'd be much more advantageous in a tunnel environment, than on an open field where wind + rain could decimate their already questionable accuracy and effectiveness. 

But yeah, at least for the beginning-middle part of the RP, my little kinsmen would be relying on axes, shields, pikes and crossbows with a few experimental weapons mixed in (such as early cannons, or early grenades). The late part of the RP would feature a more 17th century style army, with pikes and muskets fulfilling a prominent role... but this is just me hashing out some ideas. 

Truth be told, I'd be happy to keep things purely in the medieval era.


[/quote]Cannons are perfectly fine for the era of this setting.
Early type cannons were pretty much introduced around there and dwarven metalworking skills would make you cannons even more affordable.
Similarly I think you may want to switch guns and crossbows.
Discounting the siege handle, the Handgonnes were really small so you can run that in combo with shield.
Guns are actually cheaper than crossbows because they are just a metal tube and bunch of mined stuff put together in a powder.
Windlass crossbows on the other hand were much more of an art.
So I can see dwarven elites using arbalests or similar weapons which were also more effective during this time.
Albeit given how guns are all metal and stuff you can get from mines perhaps using exclusively guns is an even better idea.
It could fit the dwarven theme maybe even better.

[@White Feather]I think this haven't been asked before.
How much are you willing to support magic for this setting?
Fireball throwing mages as occasional sight in battles?
Support of minor but army-scale use of magic?
Magical creatures (like the above mentioned dragons) used in battle?
Etc.
I may have something unique in mind.
