Sure - and working at night will reduce how much glare they're having to deal with... Gideon isn't liking the daytime here, neither the brightness nor the heat.

There's definitely too much of a good thing when it comes to sunlight.

Seriously - Gideon hadn't really liked how dark Drearburh was, but the First House is kinda overdoing it. 

At least it doesn't stick around all the time.

Nighttime here's about right, yeah. 

Perfect for starting their explorations.

They'll need to be systematic about this, so Ellyn will take notes as Gideon navigates and tests the doors they come across. Her greater physicality will likely be an asset in finding ways around the occasional structural collapse they come across.

The Ninth can be just as treacherous, after all. 

Gideon also proves useful at spotting hidden things - like a suspicious gap under a tapestry, a door behind it - unlocked - opening to a long hallway, a locked door at the end. 

Interesting. Make a special note of it for now, and make sure the tapestry is tucked back into place.

Second habit, coming from the Ninth. 

Never let anyone catch you at it.

Something they're both good at. 

Indeed.

Later, they come to a section of hallway near the cliff edge that has collapsed out. There are a few doors visible on the far side, and the corridor continues around a corner.

Does it look close enough for Gideon to jump? Or - could Ellyn put up a bone bridge or something? Or another big construct of some kind to move Gideon across? 

Gideon could jump it, but Ellyn might have a hard time duplicating the feat. A bone bridge would be safer, but more obvious to anyone who comes looking.

Even if Ellyn takes it down behind them? 

There'll be marks where she roots it on either side. And the thanergy expenditure will leave traces.

Nod.

Gideon can also jump it first, check the doors and look down the corridor, see if it's even necessary for Ellyn to follow her over...

That may be the cleanest option. Stay safe.

She'll be careful. 

So: Gideon takes a nice running jump over. 

She makes it with space to spare.

None of the immediately visible doors are locked or contain much of interest. Around the corner there's a stairwell. It seems to lead to a crumbling terrace looking upwards, and several flights down it descends into other levels.

She circles back to tell Ellyn what she's found so far. "Do you want to split up for a bit, or risk someone finding the bridge?" she asks. 

She thinks for a moment. "The bridge," she decides. "There might be another way around, but I don't want to get sidetracked on searching for that now."

"Alright."

She backs up a bit to give Ellyn room to work. 

It doesn't take her long to grow a path, a twin pair of oversized skeletal arms interlaced, with the hands holding on either side. She crosses carefully, then undoes her constructs, the effort inspiring only a faint tinge of sweat.

As talented as ever. 

Then: onwards?
