Can't Unlock The Twisting Corridors in Torghast, Can't find next quest Torghast

Note: Characters which transferred from a different account will not be able to access Twisted Corridors after transferring unless a different character on the account unlocks it again. Access to Twisted Corridors is an account wide achievement which does not transfer between Battle.net accounts.

To access the Twisting Corridors in Torghast, you will need to complete a quest line that is time gated. Players who started the quest line later in the expansion may not have quests available to them that other players have already completed.

The quests were originally gated one per week, but with a recent change to the game, some of those time gates have been removed. The quest line is divided into 3 parts, which can be completed in 3 weekly resets. The quests are available as follows:

Week 1

1. Into Torghast
2. The Search for Baine

Week 2

1. Remnants of Hope 
2. Information for a Price 
3. Torment Chamber: Jaina 

Week 3

1. Finding a Witness 
2. Lest the Trail Go Cold 
3. Torment Chamber: Thrall 
4. Signs of the Lion

If you've completed the last quest for a week as listed, then you'll be able to continue with the next quest after the weekly reset.

Note: Twisting Corridors is an account-wide unlock.  Once you have completed the quest chain on a character, you do not need to complete it on your alts.  You can skip the quest chain by talking to Highlord Bolvar Fordragon in Oribos at level 60.
