Othala

Othala served as the headquarters for the Asgard High Council, which convened within Gladsheim. The Stargate was located in a meeting chamber within the Great Hall that served as a focal point of contact with the other members of the Great Alliance, and could only be accessed by members of this alliance. The Asgard were given a device by the Ancients that alerted them when the Stargate was activated, which had not occurred for millennia until Colonel Jack O'Neill's arrival, and also informed them to how many travelers were present on the journey. This allowed the Asgard to prepare for the arrival of the visitors who were met by the guardians of the Stargate.

Othala was seen in detail when Major Samantha Carter visited the world to help Thor devise a way to defeat the Replicators.

The rest of the planet was a hive of activity and contained numerous meeting halls, construction facilities, homes, academic centers and outposts of the Asgard's military. Several green parks separate the planet-sized city. It has been noted that while a majority of the inhabitants are Asgard, it is possible to notice a few members of other species.
