Going down

[Anastasia]

The creature...turns and jets forward, ripping through stone fast. It burrows down a tiny, needlelike tunnel, leaving all of you behind fast. Stone fragments are sent flying out back in your direction, easy enough to avoid but clogging the tiny passage ahead.

"...or it could do that," Miranda says, "Not even I can shoot an arrow through that with so little space."

[Yuthirin]

'Surely this will not come back to bite us in the future.' Tryll remarks.

[Anastasia]

"So...now what do we do?" Benyen asks, scratching at the side of his head.

"Try and find the fucking portal out?" Dana suggests, "Shit, we must've guessed wrong and need to backtrack a shitload."

[Yuthirin]

Tryll opens a gate back to before the sewer trip.

[Anastasia]

Nothing happens - the gate magic simply doesn't work here. It doesn't take a genius to tell something's suppressing that sort of magic here.

[Yuthirin]

Tryll will Detect Psionics to see what the hey is going on!

[Yuthirin]

Also note that True Seeing is still active.

[Anastasia]

Sure, Spellcraft or Psicraft or whatever deviltry you have.

[Anastasia]

There's a spell woven into the stones here, visible now and shimmering - under stress. It stops creatures from teleporting in and out, a single portal aside.

[Yuthirin]

Tryll will disntegrate the magical stones, then!

[Anastasia]

Okay, how big an area can you affect per disintegration and how many can you manage?

[Yuthirin]

10x10x10 cube, 2/round

[Anastasia]

It takes six disintegrations, but the stones are dust and you believe the barrier is as well.

[Yuthirin]

TRyll opens the gate again.

'Perhaps we can just pretend we were never here?' he suggests.
