Starcraft 2?

[Sedako]

Everyone seems to forget one thing about the Diablo storyline.

They are brothers. They are dead/imrprisoned, certainly. but where is the father..?
Is he the Diablo Universe Creator of all things, or a Diablo Universe Satan ?

of course, if Blizzard said they won't make anymore on the Diablo universe, I guess we'll never know will we.....

Well, there are the three brothers, but even higher in the chain of command are the 2 greater evils, which are said to be in opposition of each other.
