Finish the leather armor begun by Rejiek Hidesman

Finish the leather armor begun by Rejie Hidesman' is a quest intended for Evil-aligned versions of Gorion's Ward in Baldur's Gate II: Shadows of Amn and its corresponding segment in Baldur's Gate II: Enhanced Edition.

Acquisition
This quest is acquired by completing the unmarked quest Find Rejiek's ally, which is hinted at in the Tanner's Letter. To complete this unmarked quest, go to Imnesvale in the Umar Hills and speak to Fael outside of the Umar Inn. Purchase a copy of History of Zhentarim from him and tell him that his true name is Darcin Cole. He informs you that he can complete the Human Flesh armor begun by Rejiek Hidesman, but he needs the Blood of a Silver Dragon to do his work.

Resolution
During Chapter 5, you will need to kill Adalon to acquire the blood, as she is the only Silver Dragon to appear in the entirety of the Baldur's Gate series. Killing her is extremely difficult, but grants 54,000 EXP, 3,000 Gold Pieces, Adalon's Note and Blood of a Silver Dragon.

Once you leave the Underdark by beginning Chapter 6, speak to Fael and give him the blood.

Fael will inform you that it will take four days for him to finish his work. However, when you come to collect the armor, after handing it over, Fael will reveal that he has discovered that you are not his contact; he will summon three powerful mages and then flee, leaving you to fight his allies. One of the mages is worth 6,000 EXP, one is worth 7,000 EXP, and the last is worth 7,200 EXP. They drop random treasure when dispatched.
