I'm a mage, yes. A Charter Mage, mostly, but I have to use Free Magic to walk in Death, and the bells are infused with it, too.
Destroying the bodies of the Dead are all that anyone else can do. It's definitely not easy. It's not easy for me, either, but I can command them from a distance and more than one of them at once, which makes it easier. Still, there have been times when there have been too many, and they were too fast, and I wasn't able to stop them.
Your world is probably different from mine. But if there are any Dead or Walkers here, I'll do my best to fight them.
