Kael wants to reach a place or concept where he is not automatically the strongest, where his existence does not instantly break everything around him.
He wants:
A challenge that doesn't crumble under his power
An enemy that doesn't die from his presence
A realm that doesn't rewrite itself to obey him
A system that he can't instantly break
A story he cannot predict
A being he cannot immediately surpass
Not because he wants to lose
but because he wants to feel excitement again.
Kael isn't evil or good.
He is bored.
Unimaginably bored.
The universe, the multiverse, the hyperverse, the omniverse, the meta, the authors, the pre authors…
He beat them all.
He transcended everything too easily.
