The museum, or as they called it the archive, did not have much information about the Alchemy God prior to his ascension. Especially the parts about his time within the Royal Sprout guild were not known to many and his help during the war wasn't recorded as much.
It was clear that not much was known about the Alchemy God at all.
He had seemingly come out of nowhere for many people when he became the Alchemy God. Once he became the Alchemy God, he used the name the people used to call him, Little Flower, and made a guild with it.
That was the Great Flower Guild, which was also now used as the name of the city.
Having become a god, the Alchemy God had every right to call the Medicine World his and no one would have said otherwise. But he was not a man who wanted to rule. He was not someone who even knew how to rule.
He was a free spirit that wanted to go around helping people.
