Queen's Domain: All Mementos & the Memento Mirror

Spoiler warning: this page names every memento owner and reveals how the mementos feed into Ending 3 and Ending 4.

How the Memento Mirror Works

The Memento Mirror is the reward for the Herald of Okbujo, the boss of the Record of Sin — beating it unlocks the Dread Silver achievement, but the mirror itself is only handed over when you talk to the Herald afterward. Its hint text reads "Seek the souls you once knew."

• Use the mirror near a dead named character's body or final location. Their ghost appears.
• A ghost that gives you a reward but no memento is not done yet — you have not finished that character's quest.
• Most quest-giving NPCs only pass on after you complete their task, leave the area, and rest somewhere far away, then return.
• The mirror is infinite-use and nothing about it is missable: all eight mementos remain collectible through the end of the game.

All 8 Mementos Checklist

Five of the eight characters require a full collectible or quest chain first. Here is the complete list, where to use the mirror, and what each one needs.

The necklaces, eggs, modules, and tickets each have their own location hunts — the collectibles overview tracks every one of those systems in one place.

The slow ones to plan for

• Wourha's memento is the long tail. Players report the Bestiary must be effectively complete (one player put the requirement at 99.9%), which means hunting rare spawns — including enemies that only appear after you wake the Petrified Garden. Our bestiary hub covers where entries come from.
• Erma and Ossi end in bonus boss fights (the Treacherous Sea Prince and the Strange Explorer respectively), so budget healing items before finishing those chains.
• Aganmi's crew counts four necklaces in most English guides; one Chinese 100% checklist reports five, so re-check the shipwreck shore and the air-dash islet if his quest will not close.

The Memento Altar: Forging Okbujo's Judgement

The altar is hidden in Deimpo Mausoleum, at the bottom of the big red-water room that holds a Wind Gem:

1. Find the small room to the right of the green gem-bat statue. Its back wall carries four symbols, and the door only opens if the Mask of Second Sight has all four lenses fitted (the Magic Eyes achievement).
2. Beyond it, a hall of pale-blue flame requires air dashes — bring every Wind Gem.
3. Most players reach the room with the True Holy Sword Akunra's flight, but players have also gotten in using the Cestus uppercut as an extra jump, or the Flying Mushroom Fossil's float.
4. If the four-symbol wall misbehaves (one player hit a bug where the top symbol would not respond), there is a back entrance below the Tower of Knowledge near the prison.

Place the eight mementos on the altar in any order; Okbujo's Judgement is forged on the spot, unlocking the Most Spiritual Sword achievement. The sword starts at level 1 with 15 Power, Fast speed, and Slash plus Azure Flame damage, and upgrades like any other weapon.

What the Mementos Are Actually For: Endings

Okbujo's Judgement is one of the two swords that change the final fight against Queen Siraatsu, and the reason memento collection stops being optional:

• Ending 3 (God Slayer): beat Queen Siraatsu using Okbujo's Judgement for the whole fight, then choose Banish when the game offers the choice.
• Ending 4 (Eat): complete the 69-skull ritual first, then repeat the Ending 3 fight and choose Eat instead of Banish.

Players disagree on exactly how much of the fight the sword must do (reports range from "at least half the damage" to "every hit"), so do not switch weapons mid-fight. The full conditions for all four endings, including how Okbujo's Judgement compares to Akunra, are in the endings guide.
