I do like this idea. I don't know if extending it further to make
complicated-yet-vague descriptions about who or what's inside adds
much. But it seems like this simple hint would add some atmosphere.
For everyone suggesting OBSERVE, there are already about a zillion ways
to look into structures, which you know from studying that lore archive
you got from Oleg.
