At the far edge of the Andromedia Galaxy lies a part of space known as the *"Wheel of Time":http://www.redbubble.com/people/alienvisitor/ar....
A planet hovers within the gate, a stepping stone or guardian if you will.
Vessels entering the wheel must register here before proceeding to who knows when.
When first encountered millennia ago, the forces at work here pulled the unsuspecting into the vortex, most to be lost forever in times portal.
But now with the planet Guardia floating by who knows what technologies in the entrance, a time-map is being made to the different “timezones” a ship is flung.
The ones who return add greatly to this collection.
And maybe in the fullness of “time” all will be explained
Craft from many races share the patrol of space here, in view is an Lizarian Cluster heading for the planet.
