Arina was a close friend of the Skakdi Cedrak when he lived on Zakaz, but their relationship never progressed beyond a platonic friendship. When Spiriah began his experiments, she and Cedrak tried to flee the island, but before they could get away, Arina's foot became caught in a Muaka trap. She told Cedrak to go on without her and was captured by the Skakdi chasing them. She was later executed for attempting to escape.
Arina was a bit impetuous and optimistic, but also very sensible and could be counted on in a crisis.
