I have a mixed bag of a party. We're creeping up to the end of the first major campaign that netted the party 100 xp over two months of weekly sessions. The next thing I'm thinking about doing is having the group put down roots for a little bit. The first campaign has taken them from Teth to Ossus, Gamorr, Shola and Nar Shaddaa. I'm looking for a place where they can lay low for awhile and let things cool off. The general idea I had was for them to find a small cave on some backwater world in the Outer Rim and turn it into a fully functional base over time. I've read over the AoR book about having a rebel base with lackeys and whatnot. I'm wondering about the actual "physical requirements" to dig out the side of a mountain.
Any thoughts on how this would be done? Laser boring machines? Droid miners? Blasting with explosives? I'm kind of thinking about something similar to the base on Hoth. I just don't know how they actually built it.
