Via some elaborate tech or weapon you can research you would have the ability to destroy wormhole links between systems, thereby forcing people to have to find alternate routs to those systems or use the much slower Free Travel to move off lane between systems.


This would allow you to keep more control over your borders and give you more time to prepare against incoming fleets.


You could even have a tech/weapon to counter it that would allow you to product a single turn temporary wormhole connection between two systems with a hefty cooldown afterwards.
