Dont no if this comes under techinical or help/tips/hints sections
after i opened the chest with the ghost and kill it i went back to the chest to open it but as i did my character disappeared and reappeared on the other side of the wall. i cna move my death knight around the normal area but not my character he can only move in the area that is black...does anyone know how to get out of it?
Take your DK to back to the stairs at the start of the citadel (I think those are the closest) and click on them to teleport your hero back into the normal play area.
If you choose to enter the BF, make sure to do it with the char that's not stuck, because otherwise you'll have a chance both will be stuck in the black area...
