Black Holes and Temporary Sub-Space

[Mr. Mortius]

It might be interesting if every month or so, all the new black holes would open up wormholes to a small area of sub-space, maybe a few sectors in size. Inside this sub-region are exotic materials, and controlling a majority of the space grants empire-wide bonuses to the empire holding the most territory. After a week or two, the region collapses in on itself and all cities inside are lost. Any cities and ships inside are destroyed, and avatars teleported back to the main galaxy.
