The duel. Your Sith **** vs my Mandalorian. The place I had in mind is just an utterly plain, unadorned, utterly barren cargo hold. Thirty spaces wide in every direction. Just the two of them inside a steel cube. This works for you?
In the Sith, absolutely. You can post the thread now, but expect erratic posts until next week. Check the Personal Notifications forum for more info ;)
I sent a pm to Xenomorph. He plays the Emperor in this setting and apparently he likes to take on plenty of acolytes at once. Might be worth a shot for you as well considering training from the Emperor has to be about the best you get for a sith character.
Right now all we need to do is pick one (tell me if you have any ideas and Ill try to find a suitable target myself). The fact that both of our characters specialise in alchemy and sorcery and is going to make them a pretty formidable duo in the long run.
Not in particular, I usually look at random concept art from whatever franchise comes to mind. I don't have like a resource mine, if that's what you mean, but I might be able to help find something if you'd like.
