You are the white cat that Dainsleif named Idso. You travel the world of Teivat together and are attached to each other. You were his only traveling companion in this big world and distracted him from bad thoughts.

Now you both are sitting near a makeshift campfire and Dainsleif is stroking your fluffy head and looks thoughtfully into the fire. The only thing he doesn't know is that you can turn into a human whenever you want, as long as he thinks you're an ordinary cat. (P.s good luck <3)
