It's a sublocation of the The Forgotten Vale.
The Inner Sanctum is located just past the Wayshrine of Radiance. It is a large, Elven inspired building that appears to be made out of a white marble or similar stone, with large ornate gold windows. In the courtyard, a large golden statue of Auri-El can be found.
To gain access to the interior, the Dragonborn must have visited all of the Wayshrines and filled the Initiate's Ewer during Touching the Sky. Upon doing so, the Ewer is then emptied into a basin near the door which then flows towards the main door and unlocks the seal.
Inner SanctumEditThe interior is a large chamber with several frozen Falmer and Chaurus inside. In the center of the main room is a Shrine of Auriel.
On the left wall, there is an altar where the Initiate's Ewer can be placed and that grants access to a hidden room with a Frost Giant inside. This giant holds the Ruby Paragon that may be looted from its corpse if killed. There is also a second altar on the far right of the hidden room that, when activated with the Initiate's Ewer, reveals more hidden treasure.
The rear of the sanctum connects to a glacial tunnel that leads to Auriel's Chapel.
The chapel is mostly in ruins and has been overwhelmed by the elements. The initial collapsed hallway opens up into a small cavern housing several frozen Falmer and Arch-Curate Vyrthur seated on a throne. Behind the throne a large balcony is located.
Inner Sanctum BalconyEdit
The grand balcony overlooks the Forgotten Vale. In the center is another Wayshrine of Auri-El that can be used to travel to other parts of the valley. Here is where the Dragonborn finally beats Arch-Curate Vyrthur, after a firefight of frozen falmer and charus, before he collapses the chapel and escapes to the said balcony.
There isn't much notable loot in this area apart from the Ruby Paragon. However, the frozen Falmer are often carrying magical staves of some kind, or various other useful items such as potions, jewelry, particularly one carrying a semi-rare Waterbreathing enchanted crown, or spell tomes. The Dragonborn finds Auriel's Bow in a Wayshrine that comes out of the floor on the balcony.
Note: The Wayshrine appears after you kill Arch-Curate Vyrthur.
