The Water Damaged Corridor

Hrothgar pulled out his flint and lit a torch. He held it in his shield hand and spoke, "Rhian, you in first, then me. Enelye, you cover us from the rear. Rhian, quit shaking, think of the gold."

As Hrothgar lit his torch, Rhian lit his as well. The corridor opens up before them with the yellow light from the torches. The corridor was 10' wide and paved with random yellow/grey limestone stone. the walls are rough cut limestone. Water had been seeping in the corridor from the cellar and created a slimy green sludge on the floor. The sludge settles into a few small puddles about 25' down the corridor.

The corridor runs about 40' and ends in a carved wooden door.

Hrothgar, what do you do?
