Story[]
Normal[]
A world free of suffering and loss... This earnest wish, made by the young Queen Sphene in her final moments, was realized centuries later in the form of Living Memory, the twisted paradise behind the legend of the golden city. In order to obtain the aether needed to sustain the sanctuary’s recreated denizens, Sphene has shed her conscience─the memories she had as a living person─to arise as within the Meso Terminal a terrifying entity possessed of absolute authority. Thus empowered, she now seeks to initiate interdimensional fusion and harvest the life force of people in other worlds, and it falls to you to stop her before untold lives are sacrificed.

The Minstrel's Ballad: Sphene's Burden[]
With harp cradled in his arms, the wandering minstrel sings a sorrowful song of a recreated queen. Helpless to defy the purpose she was given, this simulacrum sought to preserve the memories of her subjects by taking the lives of innocents in other reflections. Though she met her end by your hands, had she been further along her ill-fated path by the time of your confrontation, might she have proven unstoppable and gone on to wreak untold death and devastation? Such questions play on your mind as the minstrel's verse bears you away to a world of the imagination, where you once again come face-to-face with the dread entity known as Queen Eternal...

The Minstrel's Ballad: Sphene's Burden[]
Phase 1[]
Begin by splitting your group into light parties. Shortly after the boss is pulled, Queen Eternal will cast Aethertithe. Just like in normal mode, the arena will change into a green-and-black grid and will require players to avoid the distorted parts. After she finishes cleaving a third of the arena, she will hit both healers with line stack AoEs. Both mechanics will repeat two more times before the boss casts Virtual Shift, dealing raidwide damage and changing the arena into an X-shaped platform.
The boss will cast Laws of Wind, targeting both healers with light party stacks. Both parties must position themselves on the northwest and southeast bridges, with the healers moving slightly to the edges of the platform. Once the stacks resolve, they will drop tornado AoEs that will knock anyone who stays in them off to their deaths. Everyone will also get a debuff that, once expired, shifts them in the direction shown. Return to the center of the arena, as everyone will get chained together. Once the chains go out, the DPS should go northeast, while the supports go southwest. At the same time, the boss will cast Legitimate Force, working like it did in normal mode. Unlike normal mode, she will never cleave one side of the arena twice. Dodge the cleaves and position yourself on the side of the platform to get knocked back to the opposite side. The boss will then cast World Shatter for raidwide damage and will return the arena to normal.
The boss will cast Prosecution of War, a tankbuster that hits twice and inflicts a blunt vulnerability up on each hit. It is highly recommended to tank swap instead of using your invulnerability. The party should fan out as the boss casts Divide and Conquer, which targets each player with line AoEs that inflict a magic vulnerability up debuff. Once hit, players should move out of the initial hits, as the boss will hit the exact same spots again once all eight AoEs resolve. The boss will then cast Virtual Shift again, changing the arena into two separate platforms.
On the center of the platforms there are two puddles that shift players' gravity when stepped on. Step onto the puddles to float, then head to the middle as the boss casts Laws of Earth spawning four towers each on both platforms. Don't rush to these towers right away as the boss uses Legitimate Force to sweep the platforms first. Divide into light parties, and after the platforms have been sweeped, run to the towers. Move fast, as it only takes about 5 seconds for the towers to blow after the second sweep. Tower explosions cause raidwide damage and Vulnerability Up-stacks. Following the towers, four more towers will appear, two on both platforms. Also, two random players will be targeted by a wide AoE and other two random players by targeting mark. Marked players will be shot with a wide conal AoE, that needs to be directed away from the rest, Have these players go to the northern edge of the arena by floating, and the AoE-targeted players to the eastern and western edges to make sure the AoE doesn't hit anyone else. The remaining players will soak the four towers. Following this, all players will be targeted by a personal AoE, that will drop a meteor on top of them, two times. I order to survive the next part, four meteors need to be dropped on both platforms, but no more than that. Have each player drop a meteor on the platform, and for the second meteors, go floating above the void to drop them into abyss. After this, go back down to the platforms in light parties, as the boss will then target each player separately with an instant kill-attack, that will kill everyone too close to that player. Use the dropped meteors as cover as you will need them to evade the instant kill-attacks. Since the targeted player will be random, keep the light parties together and move behind the meteors. If done correctly, the meteors will be destroyed instead. But, if at any point you had more than eight meteors on the platforms, it causes an instant wipe.
The boss casts World Shatter to restore the arena and another Prosecution of War. Following them comes Coronation. Every player will be tethered to a drone, that will shoot a wide beam from the edges, and its overall position will be determined, where the tethered players are. Two players will be tethered to a single drone. To resolve this, every player needs to move to specific spot to make sure the beams will fire harmlessly. Also, every player will be targeted by a personal AoE. For instance, those tethered to the drone in the north, will go directly to the north and northwest corner. Likewise, drone on the east is handled by the players moving to northeast corner and directly east. Drone in the south is handled by going to southeast corner and directly south and west drone is handled by going to southwest corner and directly west. By going to these positions it also ensures that the AoEs will be done as well.
Next comes Absolute Authority. Players will be targeted by AoEs they drop, flare marks and finally red triangle marks, which require the player to stand next to another player. You can either spread around to deal with everything, or you can gather up the party and use as many mitigations as possible to survive everything. At the very end, Queen Eternal uses an arena wide knockback. Another Virtual Shift initiates the ice phase, possibly the hardest part in the fight.
Queen Eternal first casts Laws of Ice, forcing everyone to stay on the move to avoid being frozen. This also generates four ice bridges between the platforms. Only one player at a time can stand on these bridges, any more will shatter them and cause players to fall to their deaths. Then, four icicles will spawn the south, tethering to either all supports or all DPS. Another set will spawn, two on the east and two on the west and these tether to the rest. These tethers need to be stretched, so that the tether line will change, otherwise they will knock their target off the arena. Be careful when stretching them, because you will need to use the ice bridges to stretch them far enough.

Behind the scenes[]
At launch, Wuk Lamat's dialogue in English was widely criticized by players, primarily due to sounding flat and their lack of emotional delivery. The release of patch 7.1 added re-recorded dialogue that featured louder and more guttural yells compared to the previous recordings, and were praised as a significant improvement. According to Sena Bryer, she lost her voice the day after recording, and kept the session a secret.[1]
