Finally got to this- had some time thinking-

Pure bloods-
Self explanatory by the name,though are rare

Hybrids-
Also very much self explanatory,more common as the war(oo war)thousands of years ago ended(I will probably have to explain the whole war thing too-)

Hermitcraft seems to have only 2 pure bloods- or 3 if we count hels(spoilers oh no-)
