uh, sacrid, you don't really HAVE to be from the void to be a voidlord, it's just that the Voidlords are unnaturally powerful for their race, and a will to dominate, thus, they discovered the Voids where they could claim it without kingdoms getting in the way, molding their empire to their will. And, these empires take a long long time to organize and build, but when you live for a thousand years, its ok

And, the dmination instinct that Void Lords have, led them to dominate other worlds. When they enslaved the current world in this RP, they shared it with the others

Void Lords tend to know they are not immortal, but some get cocky

Thus led to the downfall of the Void Lords, as an order of heroes rose up and led their servants against them. The Voi Lords fell, one by one, until only 2 were left: Hellion and Devilak. These two fled into the darkness of the Void, where they could not easily be tracked down, yet the Order did finally find them.
