Erandur refers to the temple as a ruin within a ruin. First used as a military fort, then occupied by worshippers of Vaermina, both times it has fallen into disrepair and disuse.
Long ago, a band of Orcs invaded the tower and had a bloody conflict with all those dwelling inside. As a last-ditch effort to prevent the Orcs from seizing the inner sanctum in which the Skull of Corruption stands, the priests release "the Miasma", a gas which instantly puts all those who inhale it into an unbreakable deep hibernation while also keeping those slumbering perfectly preserved. Unfortunately the longer one stays asleep due to "the Miasma", the more their mind breaks down. As such, upon entering the tower and breaking the air-tight seal, "the Miasma" dissipates, allowing the Orcs and the Priests to awaken and begin attacking in a frenzy, not able to tell the difference between friend and foe.
Erandur established a small shrine to Mara within the tower's entry hall, hoping to seek her guidance. Upon entering the shrine, the priest explains how the Skull is the source of everyone's nightmares since it devours dreams and memories for Vaermina to collect.
If the quest Waking Nightmare is completed without killing Erandur, Erandur may be found at the meager shrine in the entry hall. He is available as a follower.
Erandur states that the temple had lain abandoned many years before the priests of Vaermina began living there. This hints that the temple may actually be the fort of Dawnstar that was destroyed in 2E 283.
There is an outcropping of Moonstone Ore on the exterior of the Temple (west side).
Due to the amount of Orc invaders, and to the randomization of the devotees' races, Nightcaller Temple is a good location for gathering elven blood in the quest Discerning the Transmundane.
Always add 360 , PS3 , and PC to clarify which system the bug appears on.

PS3 Erandur may not move, and will stay in the inn, preventing the quest from proceeding. This can be fixed by fighting him and bringing down his health bar a few times. He is marked as an essential character so he will not die. Eventually, he will stand up and start walking, allowing the quest to continue.
PS3 Sometimes when Erandur goes into the temple nothing happens. This can be avoided by entering before Erandur.
PS3 The system may lock up when entering the temple. This can be avoided by ensuring that the conversation with Erandur is finished, and he is allowed to walk into the temple first (at least a 5 second delay).
PC 360 After Erandur gives the Dragonborn the information inside the temple, he may be unable to open the library as he gets stuck on the stairs.
PC This can be solved by targeting the door at the top of the stairs and entering "unlock" into the console.
360 This can be solved by running towards Erandur, pushing him upwards and towards the stairway wall. When he is at least 4 stairs from the top, he'll react and move on his own.
360 Another solution is to use the Unrelenting Force shout to throw Erandur out of spots where he gets stuck. He will resume walking on his own, and he won't become hostile. Once Erandur is on the same level as the door, if he does not resume walking, the Dragonborn can get close to Erandur and gently nudge him towards the door. When Erandur comes into contact with the door, he will open it and the quest will continue.
360 Sometimes after battle, Erandur will stop being accessible.
360 This can be solved by attacking him until he falls to his knees
Erandur may disappear when he enters the Temple.
A possible solution is to speak to him a second time outside the Temple before he enters, then wait for 5 seconds before entering. If nothing happens, he may be back at the inn.
PC Use this console command may solve the problem: prid 0024280 moveto player
Erandur may get stuck while going up the stairs after reaching the barrier at the end of the stairs.
PC This can be solved by going out of the temple and typing prid 0024280 moveto player. Upon going back inside, Erandur will open the door to the library.
PC 360 PS3 It is possible to use a Platter (or Wooden Plate) to walk through one of the grates through which the Skull can be seen below. This may be made easier using the Whirlwind Sprint shout. The fall may cause the Dragonborn some damage. After going through the grate, the Dragonborn can make his or her way back to the barrier and take the Common Soul Gem that is reinforcing the barrier to make the barrier vanish. From this point the quest can continue without needing to drink Vaermina's Torpor, as Erandur will act as though it was drunk.
Note: This is also a way to keep the unique potion Vaermina's Torpor which can be stored in chests or dropped as it is not considered a quest item. Drinking Vaermina's Torpor outside of Nightcaller Temple has no effect and it will be replaced in the inventory.
PC 360 PS3 During Waking Nightmare, after taking the Vaermina's Torpor and entering the dream-realm, manual and autosaves may cause the game to freeze altogether or crash.
A possible solution is to turn off all autosave settings while in Nightcaller Temple and avoid saving until the Dragonborn leaves again.
Another solution is to leave Nightcaller Temple, then re-enter. Doing so allows normal saves.
PC Patch Beta Version 1.9 solves the saving problem
PS3 Sometimes after killing Erandur nothing happens and the skull pedestal cannot be activated. The quest marker will stay above Erandur as if the objective is still to kill him.
PS3 There is an apparently unusable Arcane Enchanter on a table beyond the barrier. Although it first appears unusable, it can be used by targeting the green orb on the top, not the surface.
