Desairn Valley, Day 11, Afternoon
You take a boat up the Desairin river. The crew get nervous as they pass the keep, looming over the river from the cliffs, but you pass unmolested for the protection money often demanded.
The boat captain drops you off at the strange rock formation that marks the small valley where the secret entrance is and heads off, unwilling to wait and get caught in the dark.
Making your way along you easily find the spring that hides the entrance and you make your way along the low, wet, grueling tunnel that leads to the underground secret entrance.
The small landing, still lit be the floating globe, is unguarded and a single boat bumps gently against the rock.
Upstairs you can hear a few people in the great hall. The upper floor there is some noise coming from the southern room.
You can come out in either of the red circles. The upper floor is slightly inaccurate because I added and extra secret staircase, but its good enough to work with.
