So... here is the beginning of the von Deathstrike blog.
Let's get a little history out of the way before we delve any further.
Aurich von Death Strike is a Death Knight, born of the second war where he fought alongside Anduin Lothar on the fields of what is now the Blasted Lands. He fell in that glorious battle, and his soul became trapped by one of Gul'dan's death knights. His soul was later transfered to another body and put into service by Arthas.
He has recently broken free of the Lich Kings hold and is seeking vengeance for the wrongs he was forced to commit against his own kind. A vengeance that shall never be satisfied.
This is... Aurich von Death Strike.
