No - it is not a piano. (I didn't check the map though - but I remember there are several pianos located in pohate) And there I thought that once having locked in the zone it might be super easy because I remember only a few really unique things there.
In describing the zone as something the shape of a boot facing left with something dangling under the heel, would the object be in foot part of the boot rather than the upper part of the boot?
Some notable interior decor items I saw: nice "barrel back" chars, lovely green two-tier stained glass chandeliers, two (maybe more) woven rugs placed UNDER beds, not beside. But I do not think you have chosen any of these as they are not one-of-a-kind. This IS a unique item in zone central, although most if not all is outside rather than inside. But it is worth a guess anyway., Is it the grand steps leading into the large central hall and rooms.
No. You expect too much of me apparently (Or you are just waiting for someone else to say it *lol*) It truly is "the obvious". (And NO - not the piano ...)
No (although I waited for that - literally there is only one piece of iconic "furniture" left now) It is placed on the floor - yes. (opposed to be hanging on a wall or from the ceiling for example)
Just making sure we have a common understanding of "piano": https://everquest.allakhazam.com/scenery/hateplaneb-hand.jpg
