Oh yes, plenty! Kaos’ family line were decedents of the humans that were spared from the Kurosian God’s wrath. Many, many humans wanted that sort of power, both magic and status, but since humans are so unreliable and greedy, the Gods killed and banished nearly all of them. So not many humans were allowed to be allies, many had to be sneaky and attempt to steal books and whatnot to gain a semblance of what the Kuros had, but also stay low so the Kuros or their allies would strike them down.
There were very, very few that the Kuros did take in as allies, however. Humans are also determined and stubborn much like the Kuros themselves, and the humans that showed a true understanding of the Kurosian way and the balance were taught the magic and treated as allies. But they were still very low in status, so they had no say in Kurosian politics, couldn’t marry or be paired with a Kuros, and many were viewed as parasites. Kaos’ original family line (on his mother’s side) came from this, and that’s also why Havok was the first human/kuros hybrid.
