This achievement is gained once you have defeated the champions in every public dungeon in the Ebonheart Pact. It will unlock once you have received the in game 'Ebonheart Pact Conqueror' achievement.
Public dungeons look like cave entrances on your map. There is one in each territory (Stonefalls, Deshaan, Shadowfen, Eastmarch, The Rift).
In each public dungeon there are a certain amount of champions. The amount of champions per dungeon may vary. If you reach a location of a champion and it isn't there then you can either wait for it to respawn (this could take a while) or come back later.
To see the names of the champions (and the amount) go to your menu, journal, achievements, dungeons, then scroll down until you reach the public dungeon section. Look for the following in game achievements:
- Crow's Wood Conqueror
- Forgotten Crypts Conqueror
- Sanguine's Demesne Conqueror
- Hall of the Dead Conqueror
- The Lion's Den Conqueror
These achievements will also show you the progress you may have already made.

Notes:- The group event is not required to be completed for this achievement.
- The champions take a long time to respawn. I found that if one champion was not there, then going and killing another often sped up the spawn. If it is your last one left then either come back later, or just sit, wait, and do something else until they spawn.
Viewer's note: If you find issues with the maps provided (locations of champions) please comment, and give their new location if you worked it out. Thanks.
