Having successfully harvested the traps, the room is now free from danger.

Each character gains 1,400 XP.

After appraisal, the traps are worth:
Blast of Flame trap: 15,000gp
Teleporter trap: 16,000gp

The maze area, now cleared of dangers, is easily navigated until the team finds a spiral stairwell leading upwards. After ascending a distance there is a large door, though the stairwell continues upwards as well.

Listening at the door, you hear the sounds of something scraping along the material of the structure, possibly claws or scales, occasional cracking and crunching sounds, occasional thumping, and underlying it all it sounds like several creatures breathing. Rather big ones. At least Large size, but maybe bigger.

There's likely danger behind the door. You could prepare and try to take it by surprise, or just continue up the stairwell.
