Noh casts a third vote for exploring the NE tunnel. He stands at the tunnel entrance for a minute, listening to the wet, rhythmic, wheezing sound with his druid's ears. "I just don't know," he shrugs. "But I'm game if you are."
I will give each of you a chance to make an Intelligence check to identify the noise. You can roll at home with your favorite d20; try to roll less than or equal to your Intelligence. Let me know whether you succeed or fail, and if you succeed, whether your PC has ever been to the ocean in their backstory, or if they are a landlubber.
Noh fails his INT check with a roll of 12.
