Staff of Celestial Devourers

The Staff of Celestial Devourers is a magical artifact that the party was informed about by Carrie Crowlantern. 
The staff was made from the bones of the twin sons of Fenryon, Hati and Skoll, when they died, and given to the greatest archmage of the time; a man named Arcturus Slade. When he turned to dark magic, Fenryon wrestled the staff back himself, and returned it to the Lady of Ravens. 
It resembles a long, bone staff with two glowing orbs on each end; one blue and one gold. The ends are carved to resemble two wolf heads, with their jaws wrapped around each orb, facing in opposite directions.
== History ==
The staff was given to a scale war hero to stop Tiamat the last time, but the dragon queen bit it in half. When she fell, her last act of vengeance scattered her hoard across the planes. Carrie Crowlantern informed the party that the Resistance was looking for the staff and that it would be important for the fight against Tiamat.
One half of the staff was presumably lost to the upper planes. The other half in the possession of the black dragon was in the horde of the black dragon Crow. The party went on behalf of the Resistance to acquire the staff, thinking Crow was away, but the dragon had come back through the tar pits in his lair. Since he unexpectedly had acquired the Eye of Vecna, defeating the party and taking them captive was simple.
When the party woke, they were in the Vastlands some time later, having lost most of their magic and mundane items. However, for whatever reason, Crow had allowed Lucius to keep the half of the staff that he'd stolen from Crow's horde.
Much later, after the party had reached The Shaded Valley, there was evidence that the other half of the staff was probably located in The Beastlands on the upper planes. Andrith implied she thought the party could help gather an army to oppose the occupation of Tamvrien if they had the weapon. Lucius and the others decided to go get the second half of the staff so that Lucius would have the entire weapon at his disposal and so that the party could rally troops. This involved traveling first to Ysgard, through an enormous magical tree, and then through the Beastlands to "The Heart of the Forest". It was discovered that Bahamut was once a resident there, and that the staff was probably in his horde. 
The party went through a series of steps to get to Bahamut's home, and fought a number of Dragon Cultists (Mainly Crimson), demons and demonworshippers, and evil mages (Mainly Cael) who were there for unknown purposes. Finally the party got to the treasure room and found the half of the staff, and Lucius joined the two halves to complete The Staff of Celestial Devourers.
