History and specifics
Thousands of years ago, Vulpecula 12 IV supported an intelligent civilization that had advanced to the building of complex cities. Unfortunately, a meteor impact shattered the planet and destroyed all life, as the natives had not developed sufficient spacecraft to evacuate. The event left an asteroidal debris field with metallic core fragments that interfered with sensors.
In 2274, Commander Kolak’s Klingon battle cruiser used the debris field to evade pursuit by the USS Enterprise. Since his vessel's deflector shields had been damaged in battle, Kolak maneuvered his ship behind a portion of the planet that contained blocks of partially destroyed skyscrapers. At the right moment, his ship fired disruptors at debris containing magnesium. It flared, disabling the starship's sensors. By the time repairs were completed, Kolak's ship had disappeared.
