Assuming Lucifer is not destroyed - it would still be damaged, lost most of it's reacotrs...you'd think it could stand against the 1st Fleet (the best terrans got)? Could it even power up the shield?
In the first mission of my minicampaign (released in the INFA internal

), Lucy has just emerged from the node, after destroying the Bastion (which collapses the node).
Most of its reactors are down, beams are not working, it's disabled, glowmaps are off and turrets are firing inaccurately, but the shield is still up. It's attacked by 2 destroyers and... oh wait, you'll discover
when if I'll finish it.
