I realized why I kept talking about putting more seals on Belldandy if she wanted to stay with her hypothetical kids.
There's not many stories where the god lives with their kids in the old myths. I was going like they had to decide between putting more seals on that they couldn't remove themselves, but risking not having enough power if they are attacked by their enemies; or having enough power to protect their child from their enemies, but unable to interact directly.
The reason I say enemies instead of demons, is because I'm going with that some of the magical beings that you hear about in the old stories, Like Elves, brounie, trolls, goblins, and the rest of the fae, Some might decide that if the god has a child and is weakened, it's a good time to attack, even if the god is still more powerful then them.
After all, in the OMG universe, There's Lorelei, plum tree spirits, earth spirits, the engine trolls, and whatever Morgan was. Where might be more.
