In the seas of vacuum between the stars of Stellaris filled with thin misty dust, a fringe galaxy, the Old Langma nebula between sector 76 and 78, was once the home of a starfaring civilization known as the Langma Union. It did not fall to the spawn of Evil Gods, but to a manmade supernova detonation more than 300,000 years ago instead—a single flawed ritual along with extreme coincidences had sent the solar energy spell the Union used into disarray, with the extradimensional Psi effects causing a chain explosion across the twenty stars they controlled, destroying all their core domains and colonies in eight minutes.
