Not sure what you mean by 'exotic' while still being lore-friendly. Exotic implies that it stands as out-of-place in its current surroundings.

I'd recommend playing more towards wide-eyed newbie-characters rather than established legendary figures. Allows other players to take you and your characters under their wing in-character and out-of-character more easily without it looking as though someone is spoon-feeding answers to the physics proffessors.
