Attilisk:
"Well, let's find it first and we can figure out how to deal with it on the way." He slides into the hall to follow the sound that seems to indicate the direction of the Brethren beast. "Let's hope this works the way I think it works."
Attilisk holds the "detector" in his left hand, quarterstaff ready in his right. He advances slowly, constantly checking for obstacles or threats.
Ready to defend themselves, Attilisk takes point as Eleisai, Eris, Erin, Cube, Seeker, Q'nur, and Defino arrange themselves behind him. Following the pure tone, they head out of the room, into the corridor, down a segment that is slightly inclined downward and floored in something that resembles short pale green grass (though it does not seem to be alive), bypassing a sealed door that glows a soft shade of pink, and to a large square opening, perhaps twenty feet on a side, that leads to a large spiral ramp that penetrates deep into the ground. The ramp is covered with more of the "grass" and lit by a series of floating, glowing insects, each perhaps a meter long, triple-segmented and with wings that buzz constantly to keep them in place. There is a smooth synth wall on the outside of the ramp, but the inside is open, plunging down at least a hundred feet. To fall here would be... painful at best, but most likely lethal. At at least two places you can see, you spy a capsular form stuck to the wall with some kind of pale orange webbing. The pure tone seems to indicate "down" is the way to go...
