That's what you get for trusting Aeridin to let you breed, instead of looking to the mother of all baby rearing!
And who would that be?
There are a lot of orphanages - Jilseponie's in Prantz, the one Jennara built in Western Gate, the one Lyn Tobias runs in Leringard. Adopt some children.
And another thing...What about Aasimar and Tiefling? I mean, they are 1/8 outsider or less, so pretty much human... Are they still sterile?
