Saachi

Saachi, a violent race descended from humans capable of magic. Magic is produced from a "soul", which is a certain color. Darker colors are more resistant to magic but have weaker attacks, while lighter colors are weaker against magic but have stronger attacks.

Soul color spectrum:
Black hole (almost black, most defense but cannot use magic) - Ashen - Subdued - Base - Neon - Pastel - Blinding (almost white, very strong magic but almost always destroys body due to extreme magic intolerance)

Social spectrum:
Blinding < Black Hole < Ashen/Subdued < Base < Pastel < Neon
