Again, how does that disrupt canon lore and the world of RP? You are playing a High Elf, so I assume you have a background for your character to be a High Elf who is in the Alliance. A former Scourge member regaining free will and lucidity of mind and joining the others is a very basic and simple concept of the Undead race. It doesn’t send you into Minecraft or break lore in any way.
