The World Quest has been hotfixed to only award gold on NA Realms.
Midnight Season 1 OverviewSeat of the Triumvirate Overview
Seat of the Triumvirate World Quest
Hidden on the Argus World Map of Eredath, you'll notice a new World Quest for Seat of the Triumvirate that awards a 246 (1/6) Champion cloak. Unfortunately, this is only available on NA realms as the reward in EU is simply gold. It's unclear if this world quest and reward are intended, so complete it while it remains available.
You will need to clear the dungeon on either Heroic or Mythic difficulty with level 90 scaling to obtain the rewards. It won't be a complete walk in the park, but should be relatively straightforward for most characters.
Of note, some players are reporting issues entering Seat of the Triumvirate if they haven't completed the introductory Argus campaign from Legion. Even if players can reach the dungeon via the Timeways portal, they're still unable to zone into the dungeon.
