While Walker had begun tio prepare to head back toward the island where they had fought the demon lord, he realized that he should check up on a few things before he headed out. He knew that the wandering blacksmith had begun to get called on more and more even though he had been dragged in to another one of his hyper focused moments.
He had been focused on what Walker had brought to him again, but he had also begun to get caught up by more of the changes around the city. Specifically, the changes in manas.
