Static

Sometimes, W-Space systems will contain wormholes that are refered to as "statics".

Those wormhole, although they disappear with time as other wormholes, are more or less persistent : once the static wormhole collapse, another will re-open somewhere in the system, leading to a different system of same class.

For example, a Class 4 W-Space system can have a static Class 3 wormhole. As soon as the wormhole collapse, another wormhole opens to another Class 3 system.

It can be very profitable to collapse a static wormhole on purpose, because it then mean another neighbourg system - and maybe another K-Space exit.

Also, it can be used to get rid of enemy corps on alliances habiting that precise system: by collapsing the wormhole you then prevent them from getting into your system, while still having another possible exit from the system.
