I suppose if we're going that far back in time, Dorgan "The Rock" is also frozen in time hunting ogres with Highbough and Wen in (081) Journeymen Returned.
I know Chiron was up top and fled back to the boat room. I believe he's the only one. All of the others were in the treasure pit and fled down a side corridor.
Chiron hisses at the adventurers in the pit, barely loud enough for them to hear.
The dragon's mate returns! Flee now!
Chiron himself exits the room in haste and returns to the boat room. There, he draws his dagger and begins to pry the dead dragon's teeth out of its mouth.
