Oh fuck it!
[Tinfoil] EVERYONE IS A Dreadlord! The whole universe was started by a bunch of Dreadlords that were attempting to manipulate each other to gain power. Some pretended to be other races to lure their rivals into a false sense of security, but sometimes they went too deep. And their decedents just kind of forgot about it all. Now we just have Dreadlords invading other Dreadlords.
The manipulative Long Con has been so Long some people only think there are actually other sapient beings in the universe. [/Tinfoil]
