So here is a relatively spoiler free guide i'm gunna make.. as vague as possible, while still being helpful.
Play the game until you can start the quest "What Pride Had Wrought" and do whatever you must do to drink from the 'plot device', do not allow 'anyone else' to.
There is a point where a person of note, has an issue finding their offspring, afterward. Resolve it. This sets you on the path for the quest "The Final Piece". At a point you will need to fast travel to a small icon on the map (not the war table). Go there, Click the statue, watch the cut-scene, do the thing, watch another cut-scene, get the achievement.
