Ux Utanar cautiously inspects the romm without crossing the threshold. He is looking for signs that could indicate the time of the last use of the storage space. Is there dust on the floor, possibly with footprints? He extends a finger to swipe the nearest shelf and to scoop up a component pouch. Does that leave a dust-free circle beneath its resting place? Do the parchments seem to have started soaking in humidity, or do they appear crisp and rigid still? Are the tea-leaves relatively fresh, brownish and shriveled, or to the point where a light touch would see them crumble completely? Are the rations rotten, full of moss and fungus, or just a little stale?
"Alright, this space has not been visited in quite some time, but I'm not sure if we're talking days, weeks, or months here." says the dragonborn to the others with a pensive tone.

Once his assessment has been performed, Ux Utanar moves in and leafs through the notebooks, looking for a diary or an accountancy book of some sort which could provide some dates. He then comes back to the main space to observe, though from a few meters away, how 'Drucilla' is handling things.
"If one person here is able to figure out this portal-thing, it's definitely you!"
