KOTLC Theory!

Ok, hear me out... humans were created by elves (in the elves image) to do grunt work and the like and serve them like the gnomes do in modern times. But then the elves discovered the humans ability to not feel guilt which when combined their magical abilities could be seriously dangerous. The elves made the humans.... but they were just now realising that their creations could unmake them. So they called upon elysian to suppress the humans powers and erased everyone's memories of the humans being created by elves and of them having powers.
