I was just about to win a game (or so I thought) when the Dread Lords arrived. I was in the middle of a war with the Drengi, and they had several of my planets infected with spies. They ended up surrendering to me, and therefore no longer exist as a power, but their spies are still active. None of the orignal races are left, only the Dread Lords remain. (And probably will remain for awhile....)
