The Oratory of Wael

 is a location in.

Background
Perched at the top of the temple dedicated to Wael, the Oratory contains some of the most prized relics of the Hand Occult.

Points of interest

 * The Oratory is pretty simple. The lower section served as a combat arena during the confrontation with the forgotten archmage. The chamber to the northeast contains a pedestal that can be activated with Bekarna's Depleted Grimoire (must be during the night otherwise it will not be able to absorb enough starlight) and the northwestern corner has the stairs leading down to The Scriptorium.

Loot

 * The Mask of the Weyc: On the forgotten archmage.
