Are the doors the same kind of stone as the pyramid?

No - they don't absorb the light from her lightsaber nearly as much, and they seem more metallic than anything.

So probably she could cut through them? Clearing the rest of this is going to be tedious...

Well, she's gotten the pile mostly low enough she could squeeze through just the top.

Perfect. Here goes, then.

The top of the door fortunately provides no resistance to her lightsaber. There's a drop beyond that - again pretty far, but not nearly as bad as her fall onto the rubble, and this time she hits a smooth floor. There's no dust in here, too, except what she brought with her, and it's cold.

The walls look like they're made of the same dull material as the door, and have carvings in them - different from the ones on the surface. They look like potential star charts, actually, just not any Salacis immediately recognizes.

She's at one end of a long hallway, and her lightsaber's glow doesn't go far. She doesn't see any hazards right now, but - that doesn't mean there aren't any, and the hairs on the back of her neck are rising for some reason.

Brrrr. Chilly.

Hand navigation isn't her strongest point, but she knows the most common references for each sector. She takes a moment to see if anything looks even vaguely familiar. Making sure to keep half an eye open for zombies or mummies or terentateks, of course.

Hmmm...

Sort of? This looks vaguely like the charts for this sector, actually - with either a very inaccurate artist or minus at least a few hundred thousand years. 

...Huh. That's. Extremely odd.

Not quite interesting enough, though, not without a full explanation for why it's here, Salacis thinks. Which means she's gotta head further into the dark.

She gets a sense of creeping, impending doom when she's about a hundred feet down the corridor...

Yeeeeaaaah okay she's gonna stop. Pause, back up, take stock, try to triangulate to source of the doom more precisely.

It's ahead of her! Seems to be something about the corridor itself - at least, it isn't getting bigger or smaller or more or less urgent on its own. 

That's... less than ideal. Probably some kind of trap.

She doesn't have any of the equipment Kayra, her Mandalorian mentor, taught her to use, but she does have the Force. So maybe she can- set off the trap remotely?

Hmm... Maybe. She'll need to poke it a lot more - she isn't sure exactly where it is, and her sense of the hallway slips through her fingers like ink. 

Can she just... push with the Force like she's walking and move that pressure down the hall?

She successfully creates a strong gust of air! She possibly was not actually trying to do that. 

She also successfully sets off a pressure plate - but nothing immediately happens, except her sense of dread getting a little bit worse. 

Welp.

Probably okay for her to walk down the hall herself, then.

That doesn't seem to present any new problems, though it's a bit hard to differentiate possible causes of Impending Doom.

She hits a massive room before the doom catches up to her - her hallway lets out onto a walkway around a deep pit. The ceiling and floor and other walls are all outside of what her saber illuminates, but she can see the murky outlines of walkways on other levels and crossing the pit.

This place is pretty spooky.

Are there any other entrances on her level?

Not that she can see. 

Right.

She'll have to pick a level to jump to, then. Let's try... going up, for a change.

The sense of danger suddenly gets very high while she's mid-air - and there's a bright flash as blaster bolts fly at her from numerous directions. 

Eep!

She twists, tucks in, spins her blades to ward off as many bolts as she can- fortunately her weapon of choice is well-suited to this sort of defensive action. She lands in a roll on the level below the one she was aiming at, lightly scorched.

There's a moment of breathing room, a loud hum - and then another barrage.

She's slightly better set to handle this one, and there are fewer angles she needs to cover.
