Lee and Avatar both were brought to Luxium using the same ritual. Even so, both ended up differently: Lee arrived with his whole being while Avatar only arrived with his spirit, the reason for this, is the caster.

Avatar was brought by Az while Lee was brought by Ka. This is why despite using the same ritual the output was different, even when Az was a genius and prodigy in arcana, the flux and talent on his body was enough to bring a soul, while Ka being lit a god, of course has enough power to bring a complete human being.
