Igneus Orbem

Igneus Orbem, a semi-volcanic barren planet with remains of an ancient race called the Vulcagnis, is one of three planets in the Arlun galaxy that has a Stargate.

History
Several million years ago, the Ancients came to the Arlun galaxy in order to seed life to the galaxy. Shortly after their arrival, a hostile alien force attacked and demanded their withdrawal from the region. The Ancients managed to place three stargates in the galaxy before they were forced to leave.

Some time after, the planet was colonized by the Volcagnians

In 2011, The SGC had a power overload and was on the verge of destruction. Major Krieger obtained blueprints for the BC-303 and went through the Stargate along with 18 other people. He and the rest of SG-24 along with a team of scientists were sent to the planet Igneus Orbem in the Arlun galaxy.
