Okay i have an interesting ficlet challenge. We all know Arthas is dead but even though the Ebon Blade tore apart from him there is still possibly a very then invisible line making them still a part of Arthas but not under his control.
When he dies said lines are destoryed. Yet the Death Knights continue to live.
So how would your Death Knight know before anyone else that Arthas has been killed? If they didn't have a hand in killing him.
Would a small piece of your Death Knight die? Would they regain their memory? Or gain skills they had in their previous life? Or would they just feel a chill down their spine?
Have fun
