ToME: the Tales of Maj'Eyal

Were Kruk female orcs not part of Breeding Pits program? Or did they only select a small minority to become Greatmothers leaving the rest to choose other classes?
Or did Eidolon retcon the whole thing and orcs found some other way to rebuild the populace?

If I'm not mistaken, the decision to create the breeding pits is part of what caused the Kruk to leave in the first place.

Clearly, the orcs now reproduce via spores.
