The Eater of the Dead: How do I stop it?

[Lungfish]

It became No-One's prophet when it went rogue. And it was in a "Friendly" Dominion so I was screwed. Any Magi I used died from Nethgul's Soul Slaying, and any real soldiers were squished or soul drained. Fortunately it ran off after crushing 1 quarter of my empire. Of 50-125 point militias, forts and of course several powerful warriors. I just cut my losses and hid. Still, I must admit, Eater of the Dead is the most awesome summon ever. The old Pantokrator (Programming Team)was smart to banish it to outer space. It's like Cthulhu that gets BIGGER.
