They pass several empty skooma bottles, then more hallway, then a room with oil slick on the floor. As soon as Ena steps in, two portals on the walls open, and a decorated sphere emerges from each, unfolding once they roll clear. They immediately spot Ena and move to attack.

Ena jumps backwards, putting a conjured, translucent wolf between herself and the constructs. 

Elana directs a stream of flame at the oil beneath the constructs, setting it alight.

The constructs don't seem to particularly care about the fire. It does make it harder for Ena to circle around behind them, though; instead she falls back and starts peppering them with arrows, summoning a flame atronach after the familiar dies.

But Elana can use the fire to augment her spell, coaxing it into a roaring wall that even a machine must take note of.

Between the atronach and her spells the two constructs do seem to be overheating, the steam powering them boiling prematurely.

Eventually they break down, aided by arrows stuck in a few key joins.

"Well, that was exciting."

"Mmhmm." She pauses to take a proper look around the room. "Past that table, see that ledge up there? It seems to connect somewhere, might be possible to skip some of these rooms."

"Worth investigating, especially if there are more constructs."

Some investigating reveals that the easiest way up to the ledge is jumping on top of one of the pistons, then jumping off onto the ledge when it's near the top. 

The ledge has a chest and a potion, and doesn't directly connect to another room, but there's now one in view overlooking the room they were just in. Probably within jumping distance. From rubble, it looks like this ledge used to be part of the overlooking room.

Ena peers around, but doesn't see or hear any enemies in the next room, so she steels herself for the jump.

She makes ready to provide covering fire, should enemies appear.

Nothing immediately pops out. Ena takes a look around for anything hidden, tries to listen (though it's hard to hear anything over the steam in the pipes), and then gets clear of the landing and motions to Elana.

She leaps across when the way is clear.

There's a path going to their right, and a path going forward that loops around the room below and seems to connect to another door on the opposite side. There's pistons around the edge of the path around the room, perfectly poised to knock them off the ledge.

Ena points, over to something catty-corner to them in the gloom. "I'm not sure, but that looks like one of the valves that've been dropped machines at us."

"Ideas for how to convince it to not do that?"

"Probably not easily, especially without risking blocking the path. Do you have any magic that could block it off from a distance?"

She considers. "Nothing especially subtle. I could wall it up in ice."

"It's a pretty narrow space, could you keep it thin enough that we wouldn't be slipping if we tried to go past?"

"It'd be trading off the strength, but yes. It would still buy us at least a moment."

"Alright, then. We should be able to get close enough before however it senses us goes off."

Elana readies her spell, visualizing the course of it in her mind. Wall of ice, strong and firm, thick at the base and bending across the face of the vent.

It seems to work.

Good.

The pistons are a bit of a pain to get past, and when they slip past the ice wall there's a muffled thump, and the wall shakes but holds.

Nothing else jumps out at them. Past the door is a hallway with rooms branching off, all but one sealed off by rubble. Ena glides past them, then through another door, and freezes once she passes the corner, before knocking her bow and carefully sighting along it, taking out what's apparently a mechanical spider with its back to them. She holds still for a few beats, but nothing else seems to have heard.

Looking around the room, there's a gap in some pipes to the left, what looks like an abandoned camp nestled in it, and a ramp up to the right. The spider was in an alcove to the far right. There's an almost slithery, skittering sound that can be barely heard over the pipes and steam.

Sounds like trouble. She'd best be ready.

"Left or right?" Ena asks. "I'd somewhat like to investigate that camp more, might be clues as to what the danger is..."
