The company flee madly into the digging room; Boggs slams the door after Walfried then high-tails it after the rest as the dragon burst through the door behind him!
The company flee for their lives, back through the sundial room, the twisting passage and into the boat room where they finally pause to catch their breath. By this time they can hear nothing but their own pounding hearts. It seems the dragon has given up the chase.
So it's a wee foray into the pursuit game:
According to the DD, pursuit speed is four moves per turn. Assuming the players are fleeing directly back the way they came, one pursuit turn would therefore take them through four doors and almost all the way back to the entry. Doors and corners are possible deterrents to pursuit.
Okay, so four doors. 4d6=1,1,6,3. So it will pursue through one door, but no more. Excluding the door into the dragon room was burst down and not shut.
A rest and fresh torches are probably in order by now...
