First things first, Eisen started to get to work with the different 'Elemental Spirit Magic' infused materials. As the old man had expected, the materials had all become incredibly, incredibly soft, as that was just the type of element they were infused with. While Eisen's own element was a heavily physical one and as such turned some of the materials he infused it with way harder, albeit more brittle, Xenia's element was a conceptual one that let someone interact with non-physical creatures. So of course, it made sense for it to be that way.
Although the 'Elemental' part of Xenia's element seemed to add another pretty interesting effect to all of the materials, which Eisen was able to see especially in the different gems that were enchanted. While they also became a bit softer, their elemental nature was strengtehned heavily.
