A Wrested Mind

 is a fathom quest in Torment: Tides of Numenera.

Synopsis
The seal on the portal to the fathom where I met Kamose, Villon, and Diviaticu has weakened. It should now be possible to open a way back there, but no doubt the Sorrow Fragment that sealed it in the first place still remains.

Walkthrough

 * This quest won't become available until after you complete The Cold, Calculating Jack and restore Matkina. Enter the Calm and talk to the Specter to learn that the seal on the Clock Fathom has weakened. Approach the sealed fathom's entrance in the Calm and interact with it.
 * You will be able to enter the Clock Fathom again and rescue the castoffs. You can either fight the Sorrow fragments directly or delay them until Diviaticu banishes the sorrow fragments. This completes the quest and leads to the next quest.
