This is a fantastic thread so far, lots of great stuff and so many directions it could possibly go! In the grim darkness of the frontier, there is only war... I think the roster is going to be crucial in defining how the setting looks. What I think is going to be super important here is the motivations to what brings these intelligent (or not-as-intelligent) beings to the setting. This is a frontier zone, on the fringes of the "civilized" world with little in the way of luxury and much that is dangerous to the inhabitants. Why did they come here? What are they seeking? What are they hunting for? Reasons could include: Making a new home, Running from a conflict or war that is endemic in other parts of the world, Running from the outcome of a previous civil war, Running from slavery, Or simpler reasons such as greed or the desire to gain fame and fortune; maybe there is gold in those them thar mountains (Or warpstone!!!!). Maybe they are on the run from the law. Maybe they just had nowhere else to go? Plenty of reasons as to why these disparate races could find themselves on the frontier. I agree, a good, catchy name is needed for the setting. Warhammer Wild West gets the concept great but is too long, not sure if Railhammer captures the full scope enough. Maybe a good setting name that captures the "feel" of the setting? Or maybe a city (or town name) along the lines of Mordheim? I like the idea of having a "Mordheim-esque" design for the setting, focusing on a single "frontier town" that has a ton of characterful rogues jostling for control. Or maybe a few towns within a large valley that has recently discovered riches? Maybe a canyon of some sort? Makes me want to make a map!
