Had an idea while talking with someone else who didn't end up wanting to do this, now I like the idea and want to play it out-
My character would be a 'vampire' of sorts. One who feeds off the energies of pleasure and pain. Shipwrecked on a backwater planet for many years, sleeping because there is almost no 'food' there, the animal population being small and no sentient population at all.
Your character could either be another being forced down by a faulty spacecraft or stranded there deliberately or whatever, or else an explorer of some type that is investigating the planet and meets her.
Anyone interested PM me...
