This was just to entertain myself.
I love the Scarlet Crusade
and cheap action movies.
"Imprisoned in Stormwind for crimes against humanity, Arnold Menethil, the long-forgotten brother of Arthas, is freed by Scarlet Commander Mograine. After escaping Stormwind, and joining the Scarlet Crusade, Arnold sets out for Northrend to avenge his father's death. Killing Arthas (because I said he can), Arnold then returns to reclaim Lordaeron for humanity, and sit as king... while the Crusade prepares for the Great Purge..."
PS- I know that my attempt at a voice over is a rediculous fantasy/english cliche, so i added subtitles... you know, in case you want to mute that part :P.
