Asgardian Dungeons

The Asgardian Dungeons are a large prison underneath the Palace where the most dangerous enemies of the realm are imprisoned.

History
At a unspecified point in time after the Battle of New York, Loki was imprisoned in the dungeons. In 2013, Kurse was imprisoned in the dungeons. He later transformed and broke out of his cell and instituted a mass prison break/riot neccesitating Fandral, Volstagg, Thor, and other Asgardian soldiers to come down and bring order to the dungeons.

Thor, along with the help of the Warriors Three (not including Hogun) and Sif, broke Loki out of his cell so he could help Thor and Jane escape Asgard.
