There are SO many things I couldn't add in there. One, Zeno's other form is a huge black wolf. Two, he has been told from birth, by the elders of the island, that there is nothing outside of Tobira. Zeno doesn't accept this though, seeing too many holes in the things they say. Three, Tobiran weapons are unlike any other, as they can also shift to any weapon in their category (i.e, blade, staff, bow, etc). In their dormant forms, Tobiran weapons are simply decorated hilts or handles.
