“Long ago, on the far shore of the Source, a great palace was built by the elves─the Grand Cosmos, an edifice of such magnitude it was said to inspire envy in both the heavens for which it was named and the flowers that pervade its boundless gardens. As with so many wonders of the world that once was, its radiance quickly faded in the wake of the Flood, its halls falling silent, the throne sitting empty. That is, until the palace was given new purpose when a mage claimed it as their sanctuary, their only company being solace, solitude, and the legion of familiars barring entrance to any foolish enough to seek an audience.

Bosses
- Shadowbolt: Tankbuster.
- Immortal Anathema: Moderate party-wide damage.
- Tribulation: Creates five small puddles on the floor that inflict Bleeding and Heavy to players standing in them.
- Sweep: After a short delay, the Magicked Brooms on the edges of the room will move in straight lines to a puddle in their 'lane'. While moving, the brooms will damage and knock back players in their path, inflicting a stack of Vulnerability Up. When each broom reaches its respective puddle, Sweep's area of effect will increase and the puddle will be removed.
- Dark Shock: Large Circle AoEs beneath two random players.
- Dark Pulse: Stack marker on a random player.
- Dark Well: Circle AoEs targeted on all four players.
After being defeated, the Seeker of Solitude will cast Magicked Movement to teleport away.
- Storm of Color: Tankbuster.
- Ode to Lost Love: Moderate party-wide damage.
- Direct Seeding: The arena will be split into sixteen tiles, with eight random tiles becoming coated in grass. Four Leannan Seed objects will be placed on random tiles. Clicking the seed will allow you to carry it and place it elsewhere.
- Gardener's Hymn: A cast immediately after Direct Seeding. At the end of the long cast, the Leannan Seeds will sprout into Lover's Ring adds. Seeds that sprout on barren tiles immediately die, while seeds sprouting on grass tiles must be killed through combat.
- Ode to Far Winds: Eight ground-targeted Circle AoEs and four player-targeted AoEs with very little room to avoid taking two hits from the attack.
- Ode to Fallen Petals: Cast immediately after Ode to Far Winds. A room-wide AoE that leaves a small area around the boss safe.
- Ireful Wind: Subsequent casts of Direct Seeding will cause a Djinn to appear on one edge of the arena that will knock all players and seeds over one tile directly away from the add just as Gardener's Hymn casts.
Insatiable Flame: Lugus
- Scorching Left/Right: Hits the entire arena on the indicated side for high damage and a stack of Vulnerability Up.
- Otherworldly Heat: Indicated by a red marker above all players. First deals damage in a circle around the player, then drops a cross-shaped crack in the floor below each player that explodes a short time later. Damage from this attack can destroy the furniture around the room.
- Captive Bolt: Extremely damaging tankbuster.
- Mortal Flame: Applies a debuff inflicts steadily-increasing damage every few seconds, resulting in death when the timer runs out. Walking into a piece of furniture will pass the debuff onto it, curing you while destroying the object.
- If an object in the room has a name, it is valid to be walked into
- But, only one object per participant. So if someone else or a Trust NPC ignites a piano or stool, you can't also use it. Find something nearby instead.
- Players cannot transfer the debuff between each other. Keep this in mind if there isn't enough furniture for all players to remove their debuffs.
- Fire's Domain: Proximity-based tethers to each player in sequence, charging at them for moderate damage. Move away to turn the tether purple to avoid being inflicted with a stack of Vulnerability Up. Standing in Lugus's path as he charges causes moderate damage.
- Fire's Ire: After each charge, casts a short but wide cone attack at the targeted player. This attack can destroy the furniture around the room.
- Culling Blade: Moderate party-wide damage. The first time Lugus uses this ability, three chandeliers will drop into the room. These chandeliers can be used to remove Mortal Flame.
Loot
- Seeker of Solitude Card (Drops at a fixed rate.)

Dialogue
Duty Dialogue
Seeker of Solitude: Should you value your lives, you will quit this place at once. Now, begone with you! Seeker of Solitude: From ageless sleep, I bid thee rise! Seeker of Solitude: Bring unto them a swift demise! Seeker of Solitude: Look how they make a mess of my floors! Swish and flick, my lovelies. Swish and flick! Seeker of Solitude: I call forth blades to run them through! Seeker of Solitude: Brave knights of eld, tried-and-true. Seeker of Solitude: If you insist on making a mess of my palace, then you leave me no choice... Seeker of Solitude: Come, my lovelies! There is filth that wants for cleaning!
Magicked Broom: Krow ot emit! Swish-swish-aroo!
Seeker of Solitude: Such pernicious stains, you are. No matter...
Magicked Broom: Ssem a tahw, ssem a tahw! Swish-swish-aroo!
Seeker of Solitude: Ugh! Insufferable, the lot of you. I will spare you, but only this once. Now leave me be! Seeker of Solitude: Still you press onward? How foolish. Seeker of Solitude: With wings of dreams, I bar thy path. Seeker of Solitude: I conjure forth the garden's wrath. Seeker of Solitude: Hold them fast with thorn and vine. Seeker of Solitude: To death's embrace their souls consign. Seeker of Solitude: Leannan sith! These cretins have sullied the sanctity of your garden. They must be dealt with!
Leannan Sith: Come, then, little ones. Let me show you the delights of my garden. Leannan Sith: The time has come to play, my children. Hearken to my melody. Leannan Sith: Grow, my children, grow! Show them the glory of your splendor! Leannan Sith: I shall...bloom...again...
Seeker of Solitude: The garden is ruined. Ruined! Mark my words─you will pay for this! Seeker of Solitude: I summon thee from flesh of stone. Seeker of Solitude: With wings of dreams to grind their bones. Seeker of Solitude: Why do you persist? Why will you not leave me be!? Seeker of Solitude: Knights immortal, heed my call! Seeker of Solitude: Seize the intruders who besmirch thy hall! Seeker of Solitude: And by King's judgment see them fall. Seeker of Solitude: I see you cannot be dissuaded from your misguided path. A pity...
Cutscene
Seeker of Solitude: You have sullied these halls long enough. Come, Lugus! Our guests yet want for company.
Duty Dialogue
Seeker of Solitude: Go, Lugus. Turn them to ash. I care not how. Seeker of Solitude: Yes, set them alight with your undying flames. Burn bright until they are naught but cinders!
Post-duty Pop-ups
Alisaie: We'd best leave the negotiations to Alphinaud and the Exarch.
Alphinaud: Phew. I'm glad for that to be over and done with.
Crystal Exarch: Now they have little choice but to hear our plea.
Y'shtola: Perhaps now we have afforded ourselves an audience.
Duty Support Dialogue
Entering the Dungeon
Alisaie: I have a bad feeling about this.
Alphinaud: Was...was that the mage we seek?
Crystal Exarch: Well, I'd say we're off to a fine start.
Y'shtola: Perhaps. But how long our good fortune holds remains to be seen.
Y'shtola: A rather ominous welcome...
Continuing through first area
Alisaie: Magicked brooms? Now where have I seen these before?
Alphinaud: Do these brooms not remind you of Master Matoya?
Crystal Exarch: An...unexpected respite from battle.
Y'shtola: How quaint. They remind me of Master Matoya's brooms.
Alphinaud: You and I remember these brooms-and their owner-quite differently.
Y'shtola: Magicked brooms... How nostalgic.
Before first boss
Alisaie: Well, so much for the diplomatic approach.
Alphinaud: Please! We did not come to fight!
Crystal Exarch: Oh dear. They don't yet seem inclined to talk.
Alisaie: Well, it was your idea to brandish blades at the door.
Y'shtola: On your guard!
After first boss
Alisaie: I knew this was a bad idea.
Alphinaud: Wait! We only wish to talk!
Crystal Exarch: I doubt they will be quite to affable when next we meet.
Alisaie: Another chance to pique their curiosity then.
Y'shtola: Not exactly a good first impression, but it will have to suffice.
Entering the second area
Alisaie: It has to be a trap... It's always a trap.
Alphinaud: It's beautiful!
Crystal Exarch: Her Grace's gardens. As beautiful as ever.
Y'shtola: The path makes a curious pattern. Not unlike a magicked circle.
Y'shtola: I sense a malign magic in the air.
Before second boss
Alisaie: another chance to garner their interest.
Alphinaud: Is there no end to these creatures?
Crystal Exarch: I had hoped it was only a topiary. Alas...
Y'shtola: They certainly have a gift for creating familiars. If only there were not so many...
After second boss
Alisaie: Well, I'd rather not have to do that again.
Alphinaud: Mayhap now we have sown the seeds of interest.
Alphinaud: If we dried these leaves... Perhaps we could use them for tea!
Alisaie: ... Why are you like this?
Crystal Exarch: Perhaps now they see us as more than mere intruders.
Y'shtola: I've had my fill of this garden. Let us move on.
Entering the third area
Alisaie: I almost feel bad interrupting their meal. Even if they are only illusions.
Alphinaud: <gas> Gh-Gh-Ghosts!?
Alisaie: Oh come now, Alphinaud. Don't be silly.
Alphinaud: <gasp> Gh-Gh-Ghost!? ...No? Oh, thank the gods.
Crystal Exarch: Their mastery of illusions is impressive.
Y'shtola: I can but wonder how lonely they must be.
Continuing through the third area
Alisaie: Wonderful, more illusions. And now they're dancing this time.
Alisaie: Ahhh! Alphinaud, behind you!
Alphinaud: Haha, very funny. I know they're not ghosts... At least I hope they're not.
Alphinaud: Keep it together, Alphinaud. They're only illusions...
Crystal Exarch: It's as if we're glimpsing into the past.
Y'shtola: An eerie yet beautiful sight, is it not?
Before the third boss
Alisaie: Looks like they're finally taking us seriously.
Alphinaud: By the gods, they've given life to flame!
Crystal Exarch: I do believe we now have not only their curiosity, but their attention as well. <br< Y'shtola: Then we had best not waste it.
Y'shtola: Have care. there's something peculiar about those flames.
