A Cultist in the Midst

This is an Act 1 side quest that begins when you find the Cultist Orders inside a building in Burrwitch Village.

The note provides evidence that Direni is an agent for the Cult of Ch'thon and was responsible for sabotaging the water pump.

Objectives

 * Confront Direni at Devil's Crossing.

Guide
Return to the prison and talk to Direni. You can choose to either kill him or let him live. If you decide to kill him, you will have to fight him. Speak to Captain John Bourbon afterwards.

If you kill Direni you will not obtain the Strange Key from him. However, it can drop from the cultists located in the Cultist's Lair or outside the Depraved Sanctuary, regardless of whether you let Direni live or die, and can be farmed for in these areas.

If you let Direni live, or do not trigger this quest at all, you will encounter Direni again in Act 2 inside Cronley's Hideout, this time siding with Cronley's Gang, and you will have the opportunity to fight him again.

Rewards
If you kill Direni:

If you let Direni live:

Upon receipt of the key from Direni, the A Strange Key side quest will be activated, and the quest item and note can be used to find and unlock the Depraved Sanctuary.
