Possible Spoiler: Having some trouble understanding the point of the four chests and the riddle "Wisdom is the key". See they're made of four elements, and the wooden chest is already open and holds a wooden weopen. Apart from that, can't find any keys for the others in the area where I suspect the keys need to be of the same element. I'm afraid there's a simple answer to this that I can't think of. Been playing too long maybe. Would appreciate a little lift on this one. Tks in advance.
