Just in case it wasn't obvious since Trufflespeak, they want to set up a large prototype farm/plumbing complex with Fallon's help. This would be a test bed for a new self-sustaining system on the Lament, and of course would benefit the locals. I think it would be nice to improve the native infrastructure a little, instead of just using their metal to build a bajillion tanks and h-bombs.
There is also the question of what to do with the remaining parts of the twenty-thirty other truffleclubs, and the wrecked bits of junkers that they smashed in the early days. Some teachers, or a robocop or two, might be an idea. Either that, or plan A; Offer them as replacement cyborg limbs to the locals.
Mostly just posting here in case anybody else had a bright idea. *_*
