This quest must come first.
This is the start of a chained quest.
Your Link is the last of a chain of quests in Azeroth.
The quest line is like this
Time for Judgment -> Battle of Lordaeron ->
dying world(Meet Magni in Silithus) -> Heart of Azeroth(Go to the heart chamber) -> cardio(seal recovery) ->
Great Sage's Request(Go to Stormwind and talk to Halbot Wyrmbane) ->
waves of war(Attend a meeting at Stormwind Keep/Check the sailor's memory) -> Kul Tiras(Go to Kul Tiras with Jaina Proudmoore)
When you reach level 110, you must follow the quest line that is automatically given to you.
The first quest doesn't work.
So I can't go to the quest you linked to.
