Though he has little idea what could cause the ceiling to bow, Rolf hazards a guess that it's not worth tempting fate, and pulls on Bromdaeg's shoulder to keep him from nudging the sagging, wet earth.
"Aye, there's sem thin ta that." Bromdaeg lowers his pick, looking at the wet track on the floor below.
"Ah bet yer rye, an there's sem thin bait ta drip through." Bromdaeg looks both directions in the wide corridor, before shuddering slightly and moving on ahead.
"Ah, Kim en then, fair we prove ye rye."
In another twenty or so feet, the tunnel splits again, though the large hallway going right only travels another dozen yards or so before it breaks out into the light of day.
"Must be the other cave headed in from the ridge." Darran mutters,
"Let's go on to the left."
Bromdaeg continues on, every so often stopping to feel a bit of the tunnel wall or to take a closer look at a patch of earth. The slow progress ebbs away at the morning, though before too long, the group finds themselves at the opening of another room. Caught up with a wet bit of earth that reflects the sheen of the lighted ropes like a streak of silver might, Bromdaeg only sees the monster when he's already half way within the cave.
"Moradin's beard!" The dwarf curses, his pick and shield immediately coming back into position. Rolf and Darran hurry to his side, and take in the scene as they ready their own weapons.
Beyond is another large cave, much like the others they had stumbled across throughout yesterday and this morning. It is wide and deep, thirty or forty feet in each direction with a ceiling that is easy twenty feet off of the sloping ground. Curled towards the back wall, though it has to wrap itself around for lack of space, is a monstrous worm, seven or eight feet tall and easily five times that long. Its whole body is caked in wet clay that cracks off in places, especially near the thing's thousands of minuscule 'feet'. Its gaped mouth displays two rows of razor sharp teeth, though there seem to be few other features to it's face with no eyes nor ears to speak of.
Regardless of whether the thing can see or hear, it has seemed to have noticed their presence, for even as Bromdaeg pulls his shield and pick back in defense, the thing raises its head, it's circular mouth pulled open to display dozens of teeth and the semi-open cavity of its endless stomach. From its mouth issues a hissing gurgle...
OOC: Picture below that is at least close to the mark. Sorry for no map, I'm a little pressed for time. The worm's head is about 20 feet away from you (or call it 7 yards). He hasn't made any aggressive moves yet, but your instincts tell you that they aren't far off. Roll vs. IQ for me to avoid mental stun (combat reflexes nullifies the need for this roll if you have it). Let's do 3 seconds worth of action.
