Haven:

Haven is a giant station that is made of up of various pieces and parts to make up it's collective whole. It is stationed at the borderlands before you get too far out in any direction in space. That means you haven't gotten too far out where Earth is located now, nor where the Erusians, Tsivrixsh, or Cartel's worlds are located. Their Mirror counter parts which haven't been interacted with too much in Mirror Universe, but sometimes do interact with Haven due to it's placement. It's also placed in at a nice jump point for those who want to use it to try to jump further to other galaxies like trying to reach Mother's planet or other unknown places.

It can be a dangerous place for those who want to seek certain items/things, but for the most part it is as the name implies - a Haven for those who come there for safety. The various parts of the station, you can find some place in the station that you can call safe from another part.
