Royle was a member of a S-Rank Adventurers Party. As an enchanter, he was responsible to adjust equipment of party members.
But one day,
"We are the strongest party, even without your enchantment."
He was fired from the party.
Forcefully he restarted his life in a remote area.
He could make weapons that let amateurs released power beyond their standard. Using that kind of weapon, he who had no fighting experience could increase it rapidly.
On the other hand, his previous party, which lose his enchantment ability, started to lose their power and authority.
