Chaplain.

[Admiral jimbob]

Also, to be honest, adding the Chaplain as a factor in your wizard plans makes it more fun. A good Chaplain can be a really fun antagonist to play cat-and-mouse with; you have loads of ways of killing him even without spells, he can rally the station against you (it's more fun when this fails but it's fun to watch), he's kind of the antagonist to your protagonist. It's more flavour than a serious threat/consideration, but it's an addition I do enjoy. Being able to pop out of a shrub and cluwne him just isn't the same.
