No mc, that is absolutely a god. That is what gods
do.
"Hold it right there! Spirit World Legal Association! The kid made that prayer for protection under duress AND underage...and since it's a verbal contract, it's null and void!"

.........I dunno why I decided to do that gag.
Verbal contracts are very much valid, under fae laws. And gods and genies both operate under fae laws.
As for duress or being a minor, I don't think either of those invalidates contracts under fae laws. Though parents
do have the ability to make contracts on the kids behalf ("firstborn child"-clauses), so it does imply
some amount of guardianship authority (except afaik it is simply that humans can claim they own stuff they don't, and legally sell it to fae, without the fae needing to give restitution to the legitimate owner).
Either way, that god was clearly sloppy. Should have raised the kid to be ok with disappearing other humans for their own benefit.
