Delve the Third

Aldbane opens the door.

A corridor goes 10 feet, then turns south

Grampus is happy to lead the way and turn to the south.

"Light a torch for me," Golguldir instructs his hireling, Alkman, and then takes the flaming brand himself. "Now be ready your arms, and don't let anything get near me!"

All this done, he prods Alkman to follow Grampus, and follows them himself...

"Ah, south, south, yesyesyes south! Off we go, men! Mind the lamp behind!" Catweazle follows up with Ivar and Sigmund.

You see a corridor leading south. 30' down on the west wall is a door. The ceiling f this corridor, instead of being flat, is triangular peaked like a house roof.

"Lift up your torches!" Maloof commands. Can he see the top tip of the ceiling where the slopes meet? If so, anything unusual up there?

He can. It looks green and drippy

Grampus halts the march, keeping the party from the green goo. He scans the corridor with his stone-sense to detect shifting stonework, panels or drains.

"Ech! Ach! Burn it! Burn it with fire! Foulslime, fie slime!"

How high up is the slime? Would it be possible to reach it with, say, a torch tied to a staff?
