The Quest of Isaac O'Connor [Unfinished]

You walk down the path to a clearing in which you can now see a gaggle of spirits playing keepaway with some object. As you get closer, you can now see what they're playing with - one of the Scepters! Two larger spirits are tossing the yellow Scepter over the heads of the other four smaller, but quicker, spirits, and all of them are laughing. There seems to be one other spirit off to the side, looking at the game glumly.
You need to get that Scepter back. Who do you talk to?
