The divine domain of the sun and order within him worked in concert with the law fragments of light, fire, and order to make the universe mistake him for a baby star. They had a little help from a certain black orb. Now he is a star and the universe will not have such a tiny star within it. He must become what stars are meant to be regardless of his agreement.
He should be able to free himself from this designation of a star by creating his own path and gaining control of the law matrix by fusing with his own concept. In order words, he will become free when he becomes an origin god but until then, he is a star. Nothing can change that. The situation isn't that bad though. He is being pumped full of cosmic energy.
