So according to Halo: Legends in the "Origins" story, it talks about how the forerunners gathered several species of intelligent life so they could repopulate the universe after they fire the halos. My question is why didn't they preserve their own species? or did they? i'm reading the Greg Bear novels right, so if my question is answered in Cryptum or Primordium please tell me to keep reading because i don't want the books to be spoiled hahaha. thanks guys! :)
