Rook

Death and Rebirth
Following the destruction of its body, Azadiel's soul found itself too weighed down by guilt and responsibility to pass on. Bound by unfinished business, it watched over Caelynn Sylvaranth for nearly half a century. After a brief conversation with Trouble, now joined with The Huntress, his soul was visited by the Raven Queen. She showed him a possible future where his daughter was in grave danger at the hands of his adopted son, Theo Santiago. In return for his service, and for leaving his old life behind him, the Raven Queen offered to restore his body and allow him to intervene to protect Caelynn. He accepted, but the years of wandering without his body had taken their toll. He was no longer Azadiel, the father, friend, and protector. His cold, lifeless eyes echoing his final obligation: the Rook of the Raven Queen.

Rook and Jack Radigan
Leading up to an expedition into the Abyss to kill Orcus for the Raven Queen, Rook paid a visit to the Irian Investigations office in Sigil to ask for Jack's help. Following several reunions after Rook reveals his true identity with some coaxing by Jack, the two old friends get into a heated argument. Each of them say things they shouldn't, unable to see each other through their own wounds and frustrations. Rook leaves Irian angry, taking the magical items he came for and feeling himself behave like Thrane for the first time. It is the last conversation they have before Jack disappears.

Service to the Raven Queen
Following the events of Stormfall, Rook accepts his new life as the Raven's Rook. He retrieves Blackrazor from White Plume Mountain and raids the Amber Temple (to the great chagrin of Exethanter). In preparation for his next task in the Abyssal layer of Thanatos, Rook borrows some magical items from Irian Investigations and recruits the Kithguard of the previous Rook.

Many friends of Azadiel distrust the Raven Queen, and do not understand Rook's service to her. He agrees with the general consensus that she will dispose of him once his tasks are complete, but this fate does not concern him. He believes that as long as her serves her faithfully, Caelynn will live out her natural fated life. Without a surefire way to remove the Raven Queen from the equation, he is unwilling to put Caelynn at risk. What's more, for the moment he considers the Raven Queen the least of many evils, both known and unknown.
