Throne of Secrets

Description
This is an explorable area that is reached only by completing the final mission in the Nightfall campaign. "End Game" Primeval Armor is crafted only in this area.

At the end, the Keepers will launch fireworks while the endgame credits play.

Getting There
This area can only be accessed by completing Abaddon's Gate (Mission). You have to redo this Mission if you want to access it again at a later time.

Exit
One can exit the area by speaking to Volatiss, he starts the epilogue cinematic and 'teleports' you to Kamadan, Jewel of Istan.

Starting Area
This is the area where you start. There will be a statue of Kormir (the Goddess of Truth) there where you can use the emote /kneel to summon Avatar of Kormir.

Northern Path
This path connects the starting to the crafting area, and is inhabited by all the Heroes of Nightfall, as well as all of the mainland Henchmen. By speaking to the Heroes you haven't gained already, you get quests for obtaining them.

Crafting Area
By speaking to Keeper of Secrets you can obtain a Book of Secrets which can be used here at the various collectors to obtain Forgotten Weapons. It is important to note that you can only gain one Book of Secrets per character this way, but you can trade for them. You can also find here a weaponsmith and an Armor Crafter for Primeval Armor.

If you are intending on crafting any of these items, you should note that there are no Xunlai Agents, Material Traders, or Rare Material Traders available. You must have all the needed materials as well as the gold prior to starting the mission.

Southern Path
This area roughly mirrors the northern path, likewise connecting the starting area to the crafting area, however this path is empty, and is blocked by the Forgotten.
