[@Dead Cruiser]
I was considering a character that is like a savant/archivist. Someone rather intelligent and educated in artifacts, alien races, history, etc. that might be useful for a group intending to explore the unknown in search of ancient secrets and treasures. Perhaps they were a scholar or a smuggler of exotic items and artifacts previously. 

If you're looking for more of a traditional crew member/space-farer type I can do something else.
