Miasmic Gorge

The Miasmic Gorge is a large area in Darkheart Thicket. The area is shrouded in dense mists. This is where the second boss of the dungeon is, Oakheart, an ancient offspring of Shaladrassil itself.

This is where you go directly after the Sanctum of G'Hanir. Two paths deviate from this area going forward. The one to the right takes you down to the Heart of Dread, and the one on the left takes you to the Tainted Burrow.
