Fireblade? Wait... Fireblade? No, no wait. Covert team? ...Tempestus Scions? Fireblade? Stealth Suit? Do go on.
Was that a stream of consciousness? But it is sounding like the smaller scale one is the one people want so we'll go with that, but don't worry I promise it won't be all diplomacy (or even I would get bored) Also, make sure to note your caste on the character sheet.
For now it is just the 'la version of your chosen caste, but a sentence or two about how you would like your character to progress (no guarantees here, but I'll do my best) would help that along
I've been part of a large Tau military campaign RP, it didn't last. Too much conjecture and too much room to get side tracked in a large scale battle. I suggest Creative Original characters, a direct leader (Por ambassadors or low Ethereal), but with plenty of room for Auxiliaries. Ever heard of Mon'Tau? http://1d4chan.org/wiki/Mon'Tau
I have, but my group is totally Humanity Fuck Yeah. The only time I ever got them to play something non-Imperial was when we played Black Crusade, and, well. Still human/Astartes. It has interesting mechanics though.
Would you all prefer for the leader to be a player or controlled by me? At least until one of you ranks up enough to take the leader's spot.
