Sniffer and Kerwyn together strain against the weight of the sarcophagus and pedestal as they attempt to continue pushing it clockwise. After an abortive attempt (OOC: Failed Strength check with Kerwyn aiding) the arrow platform begins to move and finally stops when it reaches the "blue" corridor. Just as it arrives in this position, however, there is a cacophonous creaking and crashing from the "green" corridor and a huge cloud of dust and pulverized stone comes billowing out, covering anyone still near it. (OOC: All of you have moved away.) Those close enough can see that the entire end of the "green" corridor has completely collapsed, leaving a dark hole in the floor, at least 10 ft. wide. After the ringing in your ears subsides, you can hear a soft skittering sound which seems to be growing louder coming from this corridor.
OOC: On a completely seperate note I wanted to let all of you know that only the "green", "yellow", and "indigo" corridors have fully been explored, as far as I can tell. Let me know if this is incorrect.
