A fine detailed drawing of a Renassiance-period suit of armour standing in an alcove. But is it empty?
It might be, a display piece someone keeps around to impress. Or in storage ready for use...
Or it might have someone inside, even if it is a rather fine and expensive suit of armour for a mere guide.
Or is it a golem? A construct of some kind. Such things don't come cheap, so you might well use a valuable suit of armour to make it.
It also appears to be left-handed.
Whatever you decide is going on, it's a fine suit of armour if you permit this particular level of technology in your game.
