'Power centre' is inaccurate- that room is some sort of control area. You haven't found any sources of power.
And yes, Kosta, to the south, as I said.
Nothing to search in your room, Kosta, as opposed to Xeth's.
T is some sort of arena carved out of the rock. You can see weapon scorch marks on the wall and some loodt stains. The entry point on the left is an overlookking balcony. The way out south is not into cirridors but caves.
The life you both sense is getting closer.
I shall now provide the full map. BTW, staying together is all very well but the more time you spend here, the moe time you lose against the Dark Siders, so I recommend you all try and cover rooms as much as possible.
Actually, Xeth and Kosta could have briefly checked out all three.
J is the 'technology' room.
K, part of which is also destroyed, appears to be a large empty court, with lightsabre burns on the wlls.
L is the room partly blocked off by the darkened glass window with the button on a pedestal.
All three might be worth further investigation at some point.
Yes, in the corridors to the south of where you are, Gundy, for sure.
That corridor is also bare rock rather than construction.
'U' refers to where the pre-fabricated nature of the base runs out and is replaced by the cave system this base was built on, represented by the more squiggly outline. There is little or no lighting in there.
