[Belac]

There would also be a national ritual spell like Seeking Arrow, representing sticking pins into a voodoo doll (is it possible to create a spell that gives random afflictions instead of doing damage?), and a B/D Enslave Mind-type spell (so only a few of their commanders could cast it), representing voodoo mind control.

The flavor I am thinking of is like Pat Buchanan's slander against Haiti, where he said that the earthquake and all the other bad things that happened there were due to the Haitians having made a deal with the devil in exchange for freedom from the French. As offensive as that is, it would make for an awesome Dominions national origin...
