Bottom left corner:
Modules for a ship. Probably new starship. Looks like laser and turret lines of modules
This ship has an acryonom H - S - FF
FF could be forcefield, but the ship itself seems selected, allowing the weapon modules to be seen. So I doubt it.
In natical terms (which ai war used for the fallen spire) it could be a frigate.
New likely minor faction building: Marauder star base.
New likely minor faction enemy building.
Blue wormhole and hints of "backwater" areas of the galaxy
potential new areas of the galaxy. Speculation here runs wild. Are these areas that are not the standard owned by ai type planets? Will it be the same "plane", and border human and ai worlds? Is it a new "plane", in the process not breaking the current logic with having blue wormholes and the standard green and red ones.
