It is now noon.
A second search of the room results in no further findings of interest. As you move through the door to the north, you enter another east/west hallway. There is a door at the very east end, and 3 doors in the north wall of the hallway, one at the east end, one in the middle, and one at the west end (see the green arrows on the map, doors are numbered 1-4). At the west end of the hallway is a window overlooking the countryside.
Wirlt moves to the west door in the north wall (#1) and listens carefully at it, but hears nothing. Krislee, staying near Wirlt to help protect against any danger, looks out the window, and gasps. She sees someone climbing into the next window (red arrow) to the north along the palace walls. All she is able to glimpse are the soft leather soles of their boots, followed by the rope the person climbed being pulled rapidly up through and into the darkness beyond the window. Krislee is careful to stay out of sight of the other window, peeking carefully around the edge of the window frame, but she sees nothing further.
Discussing quietly what she saw with the rest of the party, she opines that whoever climbed must have been skilled indeed, to be able to first scale the cliffs below, and then throw and hook a line to the window sill and climb as quickly as they seemed to be moving.
