Collector's Museum

The Collector's Museum is a intergalactic vault and holding area under the control of Taneleer Tivan, used to store the various objects and specimens in Tivan's collection. It's exact location in space is unknown, but it is apparently vast with unlimited space.

History
In 2013, Asgardians Sif and Volstagg arrive at the museum to deliver the Aether to the Collector. They are introduced to the infamous Tivan by Maverdevia, and willingly give the Aether to him, not realizing that he is apparently seeking the other Infinity Stones.
