While I'm not sure all of the specifics, there are a few quests that show new characters using the Echo, or at least something similar.
What stands out in particular, to me, is in Girdania. You go to a sword sticking out of a stump, and you see a variety of scenes that you couldn't possibly see otherwise. Some NPCs are make reference that you appeared to be out of it during the scene. In the end you figure out how the sword got there without any real clues.
