The spirits (kami) that inhabit the Jwar Isles can take on all sorts of forms. There’s a spirit for just about everything. In this case, it’s the Kami of Reflection, which will be making its way to your tabletops in Bushido with the next wave of releases.
From the preview:
The Kami of Reflection is a beautiful if alien spirit. The icy tendrils that form its mortal realisation are hard as diamond but brittle as glass. As it moves the light from Amaratsu flows through its body, deflecting the energy of friend or enemy to prevent rituals and prayers alike.
