As were on the subject of gate lanes looking the same as in the rest of Sirius, if Gallia was cut off for centuries from everyone else how come you can buy the same technology in the space stations, for example Discovery Scanner - when the info card clearly states it is Order technology?
The whole concept of Gallia being sealed off and not being discovered is completely flawed, for example if they were cut-off where did the Junkers come from? They must have been able to get around the mine field somehow.
If not then they have been cut off from other Junkers for so long that they should be considered a different Gallic-Junker faction and should have different info cards to standard Junkers.
