The Pride of Yevetha, A.K.A The Intimidator, was a Mark II SSD, the only real difference being a backup sheild generator. After the Imperials revolted during the war, and took back the fleet, the headed to byss, to find in destroyed. From there, Several of the vessels went to the NR, a large group of them went to Pelleon, and the Inimidator vanished. Best guess, is that the chiss caught it, and blasted it, thinking it was a threat. The NR found it several years later adrift in the Unknown Regions, damaged well beyond repair. For once, i have no detailed info. Interesting.
