Tenebrous Depths

Description
  Powerful magic hides these ancient ruins from the prying eyes of curious adventurers. Only those who have been personally invited by the master of this place may gain entrance - and escaping it is an entirely different question. History remembers many great heroes of old, whose valiant tales mysteriously ended in these parts.  

Notes :

Notable items needed for the 'true ending' of the quest :
 * This is a dungeon that comes available with the Beneath The Stolen Lands DLC.
 * There are 2 versions of this dungeon, one is playable during the main campaign for which this page is for, the other can be started from the new game menu and has randomly generated floors, enemies and loot(which can't be brought over to the main campaign).
 * The campaign version of this dungeon contains 16 floors plus a final boss room, with a boss every 4 floors. The dungeon floors become available as you progress through the main game chapters.
 * To get the 'true ending' to this quest, you need to find 4 quest items for each respective boss, one on every floor, before fighting each boss. If you found them, each boss will drop a fifth quest item. With those items you can question Xelliren about it to convince him.
