The Spark of Life | Small quests Darksiders 2 Guide
Last update: 11 May 2016
Unlocking the quest
The mission can be unlocked after completing the main quest [The Heart of the Mountain] and starting the next one, [The Tree of Life]. Go back to [Tri-Stone] and initiate a conversation with the shaman woman Muria. Select dialogue options pertaining to Constructs, including Why is there so few Constructs?, and you'll be asked to track down a mad Construct named Ghorn.
Find the mad Construct
The location of the mad Construct is a dungeon called [The Scar] (the above screen). It's situated in the southern part of the Forge Lands, east of the Cauldron which you've visited in the course of one of the initial main quests.
Eliminate the mad Construct
The Construct you're looking for is Ghorn, and to get to him you have to go through the whole [Scar]. I recommend reading the detailed walkthrough of that dungeon - has all the instructions needed to defeat Ghorn.
Return to the shaman woman
After eliminating Ghorn, make sure to explore the whole dungeon before going back to [Tri-Stone] to talk to Muria. The rewards for completing this quest are 548 XP and 2500 gold.
