History
At some point before January 2386, Thot Trom's Spetzkar took a beating at Mazlas. When Trom advised his chief engineer on the Tajny, Solt, that the journey through the artificial wormhole into the mirror universe might be rough, Solt replied it would not be rougher than the beating they took at Mazlas.
