The Yorktown arrives over Iasii VII, an uninhabited Class-O planet, to determine the presence of dilithium deposits beneath the surface of its ocean. However, what they find instead is far more than they could’ve bargained for; a massive, undersea vault, easily predating known Annexari history by at least 1,000 years. And with the further discovery that the vault contains air pockets after all this time, an away team led by Commander Karibuchi is beamed down, eager to plumb the secrets of a long-lost era in Anexari history. However, this vault is harboring a sinister secret, one which the away team is unfortunately exposed to first-hand when a mysterious relic causes all of them to start coughing uncontrollably. After being beamed directly into the Yorktown’s</em< quarantine facilities, it’s discovered that the away team was exposed to an ancient biogenic weapon, one that causes the formation of painful blisters on the lungs. If not treated, the away team could very well perish, and so the race is on to find a cure... before it’s too late for Commander Karibuchi and her crew.
