Communication

Doesn't the Queens party have a pair of boxes that can shuttle messages to one another over infinite distances?

Also, the Brooklyn party has a cup that can send things to a dungeon in Aege from anywhere on the plane. Unfortunately, no one is ever in Aege. But still, you get the idea. I guess the now retired Tobin hangs out around there. We could give another party the cup, then the Doodya could tell Tobin and Tobin could tell someone else? In anycase, returning missives would be tough, because the cup kind of empties to a point in the middle of the room.
