The quest chain continues, the next one (The Violet Eye) asks you to speak with Archamge Alturus outside Karazhan.

The chain continues with several more Karazhan quests, the end reward being Violet Badge, a 36 stam, 45 arcane resist epic trinket.




A few notes about this chain:

1) To enter Shadow Labyrinth, you need the key that drops off the last boss in Sethekk Halls - Talon King Ikiss. Only one person in the party needs to have the key for the group to enter, but it is a good idea if you get the key for yourself as well.

2) To enter Arcatraz, you need a key as well. The key can be aquired by completing a series of quests that begins with the Aldor/Scryer quest chain Assisting the Consortium. You also need a flying mount to get into Arcatraz.

3) To go to The Black Morass, you must complete the quest Escape from Durnholde (Dungeon) in The Caverns of Time - Old Hillsbrad. This is the quest where you have to escort Thrall through the instance and fulfill his destiny. You must also complete The Opening of the Dark Portal (Dungeon) while in The Black Morass.
