Z1-series astromech droid

The Z1 was a series of astromech droid introduced during the reign of the Galactic Federation Triumvirate, shortly before the Sith-Triumvirate War. They were somewhat rarely used when compared to the Y3-series, which had been released only a year prior, and therefore were produced in much lesser numbers.

A year before the first battle of the war, one of the rare droids was acquired by the young Jedi Knight Calen Solayr, and become one of his most trusted companions.
