ISD Unknown - Battle of Tegris

One of the mentioned battles between the Sollan Empire and the Cielcin. Fighting took place in the Tegris system.

Like most of the men on Belusha, Daru had been in the legions. His century had defected, stolen a courier and blasted off after the Battle of Tegris. They had been captured, and every one of them sent to Belusha, where they had been split up, distributed across the planet’s surface. Daru himself—a round-faced, honest lad from some backwater Lorian had never heard of—had only followed his officers.
