Talk:Legion Retribution

"To the east can be found a gully full of Aetherfire. Halfway there is a trail branching off to a small side area with several manticores. It terminates in a MINE ENTRANCE leading to the IMMOLATION, which is unlocked during LEGION RETIRBUTION Act 4 side quest."

I have attached a JPG of the area. I have the quest yet there is no mine entrance.

What am I missing?
