Which Might and Magic universe are you referring to?

Kappa is the original name of the creature. And please, don't confuse Buddhism with India. Buddhism also exists in Japan, which is why Mizukami might seem to have an Indian appearance to you, but that's just your perception. The Priestesses, as I already mentioned, look quite normal, in keeping with the faction's style. They might remind you of Medusa, but again, that's just your perception.
