Messor

Messor, formerly Ord Messora, was a sparsely populated stone-and-glass world in the Outer Rim's Ojoster sector. The planet's surface was comprised entirely of rocky mountains as well as deserts of pure glass thought to have been the result of meteor bombardment in the world's primordial stage. During the New Sith Wars, Messor was discovered by Republic military scouts, resulting in the planet becoming home to a number of research stations and mines. During the Rise of the Empire era, it was controlled by a military dictatorship and defended by the Legionem Messora, which was believed to have originated as a rogue Republic military unit. Messor's most notable landmark was the Messor Arena, where mercenaries and warriors from across the galaxy including many Mandalorians traveled to train in the arts of ranged and melee combat. Due to its popularity as an interstellar training ground, Messor was also home to a number of factories that produced various training droid models.
