The Deathbringer Company will appear northwest of where the party took the quest. They are a regular Tormentor group and if the party has reached this point they should be comfortable disposing of them. There is one patrol that roams near where they spawn so just watch out for them. After The Greater Darkness and his minions are slain, a Ravenheart Chest will appear, which offers Torment Gemstones for all party members. Also, the path into The Foundry of Failed Creations will be opened.
