Introducing the Gatekeeper
The only vessel capable of sending ships to and from the home realm.
given the correct coordinates in space this ship can open a gateway to any location in this realm or any other.
It's location is known only to it's crew.
Captain's are only given coordinates of where a gate will open.
It's twin power cores give off so much interference that you can't get a fix on location when on the other side.
Due to the uniqueness of the cores the interference is asymmetric.(can't pinpoint location from interference pattern)
The only threats to it are what comes through the gateway.
