Well, the monsters don't have access to the ruins, but they still know of the door's existence. What's to say that one monster could have been loitering near it when suddenly the soul popped out because a monster native to the ruins (most likely a loox or migosp) could have snuck it through without anyone noticing? That's possible, although highly coincidental at that.
