Their are five categories though: Virgins (humans that have never had sex), Worriors (humans that have fraught or done something to do with fighting in the war), Healers (humans, like doctors or nurses that help people heal, can also be veterinarians), Philosophers (humans that have taught something, like a class) and Guardians (humans that have had something to do with looking after people/minors). Humans have to be sacrificed in a cirtain way for the Darach to get the power. People call it, the threefold death.
