Actually, I think that a unique Royal Guard would be better. It normally represent the Aristocracy (and requires this civic, which is Alexis's favorite despite loosing out on the food that could otherwise become xp. Its technology, Monarchy, is also a prerequisite for Feudalism.), which happens to be a unique Vampire aristocracy in this case. Also, the Guardsman promotion and spirit magic don't fit a Calabim aristocrat very well (they are about sacrificing others for their good, not themselves for the good of others, and spirit is the magical sphere opposed the Calabim's representative sphere, body), so I think they should be replaced with the Vampire promotion and another different magic spheres. I was thinking that body, mind, and law would be nice (it would be kinda boring if their spheres were the same as the Vampire unit's). It also might be appropriate for them too to be able to upgrade to Vampire Lords.
