The party follows the dug out passage as it winds its north, but the party soon come to another problem.
The passage crosses over a 10 foot wide split in the floor, looking down its pitch black. It’s not clear at all how deep it is but you cannot see the bottom. If you can cross the split you can continue north.
As you’re stood next to this hazard you all hear a noise behind you, a clicking scraping noise that echoes down the passageway.
What do you do?
