I think i have a good event...First yall set a portal in the arena...In this event the horde and the alliance work together to save Sylvanas...We go back in time to help Sylvanas from Arthas...Then something happens to the raid of horde and alliance...All of a sudden Arthas kills the whole raid with one blow then he gets Sylvanas and kills her...Finally she is no longer a huminoid..she has turned into and Undead and the raid has to fight to kill her...when they kill her they find that Arthas has gotten to the sunwell and corrupted it then the entire raid dies and sent back to the normal time
note.This event was from my imagination and i got bored so i came up with an event XD
