A Dark and Stormy Night
The storm rages on outside, the garish illumination from the lightening outside Béar's window alternating with slightly longer periods of pitchy black. The hallway is dimly lit by a few slow burning candles, but has no windows. Though he investigates carefully, the smell is thick enough on the first floor that it is impossible to determine exactly where it originates. The smell is noticeably less intense on the ground floor, and fades to non-existence as Béar ventures away from the stairway in any direction.
Scath will find that while the smell is stronger in the garret, he also is unable to determine the origin. The garret is a large open area with a few curtains set up to give the children some privacy (they sleep up here as well) and Scath's ability to move with stealth is more than a match for the sensibilities of the exhausted youngsters. He is able to investigate every inch of the garret and to determine that the smell is not coming from anywhere there.
