Are you taking 10 overall or taking 10 on each square with stuff in it? … ie about half an hour all up.
Taking 10 overall will give you this info:
It appears to be a storeroom for alchemy supplies … there’s lots of different stuff. Containters of worms, insects, anatomical bits from different creatures, etc.
If you want to take 10 on each square with stuff in it, let me know.
