I have mentioned before that my sons and I are getting into two new genres these days: Warhammer Fantasy Battle and BattleTech. Now, I like the settings for both, but I got to thinking how cool would it be to combine them?
I'm starting off the setting with the Empire. Essentially, the Empire is a large volume of space roughly in the center of the galactic arm. It has been divided up into a number of smaller (though still quite large) regions. these include Reikspace, Middenspace, Nordspace, Wissenspace, Stirspace, Talabecspace, Ostspace, the Ostmark, MootSpace, etc. One region for each of the provinces in the Warhammer Empire, you see, usually substituting the word 'space' for 'land.' Each of these regions has many planets within them. These planets take the place of the various cities and towns of the Empire in Warhammer. So, Bogenhafen is a planet within Reikspace. Altdorf is the Imperial capital planet. Nuln is a major industrial planet, and so on.
Each region or planet's Mechs will be painted up in the WFB state color schemes.
I figure the Knightly Orders can be semi-autonomous units, with fortress planets as bases.
Orks will be wandering raiders, mostly, based off planets out on the fringes of the Empire. Dwarfs will also have heavily fortified industrial planets in systems loaded down with asteroid belts and such. Wood Elves will be based on naturalistic planets, hidden within nebulae and such instead of a forest. Brettonia will be added, similarly to the Empire. Tilea and Estalia too.
For the other evil races, I have thought of the following: Dark Elves and Chaos are easy, just locate them in the appropriate stellar geography. Skaven are troubling. Maybe a lot of beat up vehicles and only a few Mechs? But where to locate them? Dark planets? Subterranean in human planets just seems a little... maybe in asteroid belts or gas giant moons in the systems. Undead are a problem too. Zombie Mechs? Not very sensible.
So it isn't perfectly worked out yet. But its the germ of an idea that may be fun.
