Can the Children reproduce? Like, bear a child with a mortal that would also contain some of their powers?

Well, it varies from Child to Child, depending on how humanoid they are and what they've got under the hood. Males can impregnate mortal women, although the results are messy, the mother always dying in childbirth and the child not surviving its first week. Female Children can't at all. Transferring power is a complicated and unfortunately fatal process for mortals in most cases.

That's my thought right now, anyway. I'm conflicted on the issue, so I might be swayed otherwise.
