Calle Tarnoc is wild by nature, but has had its behavior modified to accept the presence of humanoids by an intervention. It is trained against its wild instincts to accept humanoids. As creature handling goes up, a member can better empathize, train, and manage this creature's behavior. Untrained (+0), this creature will do whatever it wants and one would be helpless to understand why, with its natural disposition taking over. As creature handling skills improve, a member can understand, care for, and better influence this creature with full control achieved with mastery (+5) of creature handling.

Calle Tarnoc is the average size and body mass for a Nexu, with a balanced build for mobility agility, and power.

Calle Tarnoc has typical coloring and physical appearance for a Nexu.

Calle Tarnoc has a knack for somehow always finding a way out of situations that other Nexu tend to struggle with. This could be anything from breaking or slipping out of a physical restraint (like a shackle or collar) to wriggling out of a spatial restriction (like a cage or room). This can make it difficult to keep control of Calle Tarnoc and keep them in one place for too long.
