The Demon of Beta Gamma

The Federation starship USS Yorktown, commanded by Captain Baarry Giotto, arrived in the Beta Gamma star system. There the Yorktown found the Beta Gamma starbase destroyed. Suddenly, an alien obelisk showed up. The USS Yorktown went to Red Alert, powered up her weapons, and raised her shields. The obelisk attacked the Yorktown. A fierce battle ensued! The USS Yorktown fired photon torpedoes at the obelisk, destroying it. The obelisk turned out to be a Borg obelisk.
