Right, you could do an Atlantean civilization from 50,000 BC or something. Lots of possiblities.

There was a book series years and years ago by Julian May about convicts sent back in time to the remote past who form a colony and discover there is already an elf-like empire there. Maybe I'll re-read those books and see if it sparks any ideas.
