Chittering

SPACE Garn looks about the cave, scratching his head in bewilderment.
SPACE “Where did they all go?” he asks Alasdair. “Into the cave?”
SPACE Behind him, Alasdair is spreading sand with a palm leaf. He is covering up all the footprints and sign that anyone had entered this cave.
SPACE “When I left after you,” the bard answers Garn. “The Wise-Twins were exploring that water filled passage. I guess they went further down and the others followed them.”
SPACE The burly fighter grabs hold of his sword and strides over to the tunnel in the rear of the cavern. “Grant?” he calls out.
SPACE “Better follow them,” Alasdair says. “I don't want to be here alone in case those five guys find this cave.”
SPACE Taking the bard’s direction, Garn enters the water-filled hallway. Alasdair grabs a burning torch from the fire and follows behind.
SPACE The tunnel comes to a split up ahead, where the main passage continues on and a second passge branches to the right.
SPACE The passage that branches immediate to the right seems to have a definite direction of flow to it. Large ripples, and sometimes even tiny whitecaps, emerge from the watery surface as far back as can be seen. A splashing sounds can be heard echoing from down this hallway. It sounds like falling water.
SPACE The passage up ahead branches again. The right-hand branch breaks in half yet again. The left-hand branch seems to open up into a larger area, possibly a chamber of some sort.
SPACE You look at one another, trying to determine which way the rest of the group went, when a loud chitttering sound fills the hallway.

SPACE You both freeze. The echoing makes the sound hard to trace, even hard to recognize, but it almost sounds like—

SPACE Spiders.

SPACE Big, dog-sized spiders with hairy bodies and glistening dark eyes. They are fast approahcing you from the right-hand tunnel. There seems to be a half dozen of them, at least, and they are scurrying quickly across the ceiling towards you.

SPACE Garn freaks, allowing a scared yell to escape his lips. His knees appear to buckle, but he tightens his grip on his weapon and holds his ground. He looks at Alasdair out of the corner of his eye, apparently awaiting instruction.

SPACE Alasdair tenses up, looks to the arachnids quickly bearing down on them, and screams.

SPACE “Run!”
