A more thorough search of the rooms along the main hall fails to yield anything of interest.
The group expands its search out into the courtyard grounds and does eventually turn up something of interest. Carefully stashed away in the long-abandoned hearth of the kitchen is a large leather sack. Judging by the grit and insect droppings on it, the sack has been here for a number of years.
The sack includes two fifty foot lengths of rough but servicable hemp rope, half a dozen rusted (but also servicable) iron spikes, a heavy hammer, a lantern, three flasks of oil, and two dozen candles. Also in the bag: a small wood case with a magnifying lens (about the size of a human's palm) - probably quite valuable; a brush (similar to a large paintbrush); a small, latched metal box containing two stoppered glass vials wrapped carefully in linen (Pyior judges that they're likely potions...and different types judging by the color).
