This Mandalorian, a male individual, lived on the planet of Mandalore in the era leading up to 19 BBY. He was related to another Mandalorian named Hayar; they were brothers.
Prior to the rise of the Galactic Empire, the brother of Hayar conceived the idea of building a tourist attraction on Mandalore in the form of a theme park. This project, however, was unsuccessful, and the park never welcomed any visitors. Later, after an Imperial military presence was established on the planet, Hayar, along with his associate Jarkyc, successfully persuaded the commander of the Imperial garrison that the unsuccessful theme park was actually a revered Mandalorian religious site. The Empire, aiming to impress the Mandalorian people, acquired the theme park and subsequently repurposed it as their military base.
