- Lab 3 involved thanergy/ thalergy loops with a lot of control needed - could possibly adapt that somehow, do a very careful demolition just along their path...

That seems the most likely solution. Unless they're meant to figure out how to predict the maze's timing and run it that way.

Sensing the flow of thanergy, maybe. 

Something like that. But nothing says they can't do both at the same time.

Then let's get started. 

Ellyn starts small, which turns out to be a good thing, because the forest starts fighting back when it's wounded. "Didn't we already do this?" she complains, dodging back from a lashing tendril.

"More advanced challenges for the same underlying principle!" she says, after they get clear of the first attempt. "Hmmm - it might be less inclined to attack just me? If you're the one it thinks is injuring it."

The bones stop rattling when they're out of range.

"It does seem less aggressive," she agrees.

"Charging into danger is my job - and you can use transference to negate any issues caused by distance from the field."

"All right, my cavalier. Prepare yourself."

Eager grin. (No wiggles because the teenagers are watching, though.)

(The teens are somewhat suspicious, regardless.)

This arrangement works surprisingly smoothly. Or maybe not all that surprisingly, given the time Ellyn and Gideon have spent practicing. The hardest part, really, is keeping Gideon's path clear. It's made easier when Ellyn has the realization that she doesn't need to fully demolish the spikes, she just needs them to stop being spiky. If she doesn't excite the thanergy all the way, it just- denatures, drifts apart like so much dust. Works better on the blood, too.

Piece of cake for them. 

Comparatively, sure. Ellyn's sweating blood by the time Gideon gets to the far wall with the safe.

It doesn't seem to be locked, at least. Just a wheel that spins to open the door.

She'll do so! (Hopefully it doesn't explode.)

It does not! The rest of the bone forest retreats, and she's able to peacefully recover the key.

Nice! 

Time to step out and see how the others are getting along? 

Suppose so. Maybe someone else will have actually finished as well.

Fifth's easy to check, then Sixth and Third are working down the same hall - makes sense to hit them in more or less that order. 

Abigail and Magnus are still occupied when they go to peek in the door-

-but then there's a loud commotion from the other hallway.

She'll very quickly lead the way in checking on that!

On first inspection, it appears the bone monster from Lab 2 has gotten loose and is attempting to wreak terrible vengeance on Lab 9.

Well, good thing she brought her longsword - she calls, "Transference!" at Ellyn as she draws it.
