Rod of Celestial Devourers

An artifact associated with the Raven Queen. The staff is in two pieces, with one formerly in the possession of Crow (now Lucius) and the other supposedly in one of the upper planes. 
The party travelled to Crow's lair in the Drakelands in order to retrieve one half of the staff, on the request of Carrie Crowlantern. When they reached the staff, Crow attacked and captured the party, robbed them, and apparently dumped them out in the Vastlands. He gave Lucius his half of the staff to use, though precisely why Crow was so generous is somewhat unclear.
