Illya smiles as she watches from behind. They might have been mercenaries, but they were also family- and a good-hearted family at that. The lights dance about each wall and corner as Illya walks alongside Sarad. The corridors were narrow, and littered with destruction and decay, and had Illya's newfound friends not been so quick and skilled, she might have felt safer by herself in the dark where she was a less discernable target, being the only one who needed no light to see. However, the last skirmish had left her feeling safer than she'd ever felt since she'd awoken, and now that she'd seen them in action, the Mandalorian arms that she'd found so intimidating were quickly becoming a source of reassurance for her. Even Sarad's rotary repeater was leaving her with a sense of shelter because of its bearer.
Occasionally Illya stops to check a debris pile or corpse, hoping she isn't overlooking something important. One of them, she finds in an obscure corner with another lightsaber (although this rusted handle, apart from its crystal, looks like it has seen better days), and a security-card (among other things). Then as they reach a closed door, Illya and Burk'yc do their best to push open the door while Sarad covers the entrance, and Atin their retreat. Their efforts reveal a disused inner sanctum. Dim lights and iridescent edging light up the control panel toward the far side, and an enigmatic dais serves as the centerpiece of the octagonal room. Illya walked across, keeping watch of the dais as she crosses the room, and switches on the auxiliary power. Computer screens stirr to life as the control panel reveals its purpose as a central kiosk. The others move to join Illya as she waves them over, and for a moment, Illya thinks she can sense a figure peeking behind the corner of the entrance they'd entered from, but as she looks again to get a better glimpse, she senses nothing there. Merely a strong presence near the entrance of something once there, but gone.
"I hope this place isn't getting to me already," she thinks to herself. The lights are dismayingly sharp in the otherwise pitch black of the lightless chamber, and slowly the ceiling lights flicker to life. The illuminated room then reveals what had been increasingly bothering Illya since she'd begun checking the bodies they'd moved past. Bodies that seemed to have been of people minding their own business before dropping dead suddenly in their tracks. Some lay tipped over small drops along the edges of the floor, clasping throats or heads in anguish.
"It's like they were all mummified, and then the sith moved in," comments Illya, "I mean, I expected to see blaster fire or lightsaber scoring in here, but now that I think about it, I haven't seen any except our own since we entered this secret labyrinth. Just dead Jedi and Sith traps. Its like they never even fought each-other in here. Do you suppose the weapon's fire we saw earlier was from tomb raiders who got killed by the sith traps and war-droids they left behind?"
Illya then turns to console to access it and finds yet another barrier. The console is in fact locked by codes and interface barriers, and even the security key she'd found earlier is proving only enough to unlock the main directory and little more.
"What I'd give for an astromech droid. Are any of you proficient with computer security?" asks Illya hopefully.
If someone wants to, I figure that if someone tries to hack it, they'll find evidence of someone having already hacked much of the system, and they'll find messages of the Jedi's plan to bait Lord Nihilus into attacking them there because they didn't think they could possibly be taken so easily (and securing local treasures like their holocrons), and then of Nihilus razing the planet and draining it of life from orbit. Don't feel like you have to use my premise though. I like your ideas too!
