The USS Challenger-A has just finished its mission to the Klingon empire. It turns out that the reason for the conflict between the Klingons and the Xarantine was caused by a mysterious 3rd species that used personnel cloaking technology while their ships moved between normal space and underspace. This species boarded the Challenger-A and one was captured which resulted in open conflict between the crew and the aliens. Once it was clear that they were losing, they started their self-destruct sequence and proceeded to ram the Challenger with their own ship in the final moments before explosion. Numerous members of the crew were injured, including Cmdr. Tel-ar. The crew is now busy repairing the ship as a new peace settles among the Klingons and Xarantine for the first time in 250 years.
