Handsaw

Handsaw is Isen's familiar. It most often takes the form of a celestial barn owl perched upon Isen's shoulder or forearm. However, it has many forms depending on its master's wishes - it's appeared as a raven, a black cat, a snake, and a bat.

Handsaw can communicate with Isen and, although it is not an especially intelligent beast, it unfailingly obeys Isen's commands and wishes to the best of its ability. While in its owl body, Handsaw tends to spend time alone hunting, though it does not actually need to eat.
