Shaco lore

Imagine Shaco being just a ton of souls who were sacrified to stop a Demon. However, the Demon still needed much more souls. This is where Shaco appears (not itself), a powerful mage who decides to create a doll trying to seal the Demon using it's own soul for it. After the Demon being trapped in the doll, people try to burn it thinking it would bring peace to everyone souls but the Demon already has taken control of the doll turning into Shaco, killing everyone who tried to seal it.
