Seven silver dragons have been added to Patch 6.2.2, including three in Nagrand. All three areas require flying so I hope you’ve already completed the Draenor Pathfinder achievement.

Fel Overseer Mudlump is located in the non-instanced version of Hellfire Citadel.

Venture behind the the Dark Portal to find three rare elite Bleeding Hollow orcs. In other words, the area we first quested though at level 90.

These controllers are part of the Iron Armada achievement but you’ll have to wait for Winter Veil to collect the other two.
