Mass Effect: After Armageddon
The Annos Basin is a star system that contains the salarian homeworld, Sur'Kesh.
The mass relay in this system was the third to reactivate after the Reaper War with repairs completed in 2188. Salarian engineers also managed to make a direct link to the Sol System relay, although it remains unknown how they acquired the resources to achieve this feat given the relative scarcity of reaper technology believed to be in the Annos Basin after the relay network crashed.
