Nightingale Hall

 is a cave located in.

Description
The cave is located south of Riften. Nightingale Hall is the headquarters of the Nightingales, a small secretive internal sect of the Thieves Guild, whose primary purpose is to protect the Twilight Sepulcher, the primary shrine of the Daedric Prince, Nocturnal. It also serves as a secondary shrine to Nocturnal for the Nightingales.

It is only accessible after starting the Thieves Guild quest Trinity Restored. On the first visit there is very little of interest to speak of inside Nightingale Hall aside from some bed rolls, two chests with some minor loot, and two skill books: The Red Kitchen Reader and Purloined Shadows.

The interior will be in a state of neglect and disarray, with a bed smashed by a roof collapse, a bookcase upended etc. When returned later there are a few changes including a bookcase and nightstand with several interesting books. During the Trinity Restored, the Dragonborn must activate the armor stone inside to receive the Nightingale Armor.
