Find Kesh at the Peryite Shrine

Walkthrough
This objective appears in the Quest Journal when, after reaching level 10, the Dragonborn encounters an Afflicted Refugee who makes some remark about "ogling the grotesque". Pursuing the conversation, the Dragonborn learns that the man is suffering from the plague and would have died years ago without the protection of Peryite.

Find Kesh at the Peryite Shrine
The Dragonborn can then either kill the afflicted or allow them to continue on their way, the location of the Shrine to Peryite having been added to the map.

Travel there and talk to Kesh the Clean and continue with the quest The Only Cure.
