How to make use of corpses?

[llamabeast]

I'm playing in a game as Sauromatia, and there are lots of corpses around. In my previous game I was Ermor, and they were great for reanimation. Obviously I knew I couldn't reanimate as Sauromatia, so I thought I'd cast some "Raise Soulless" spell... only to find there doesn't seem to be one.

So, apart from Carrion Reanimation (too high research), raising them in battle (the province is not about to be in a battle) and Feast of Ravens or whatever it's called (seems hopelessly inefficient), what can I do with the corpses?

Cheers,
