Torment: Tides of Numenera

You need to unlock all elements of the Labyrinth. The achievement is counted the moment you enter the Labyrinth after the battle in the Memovira Fortress. Below I list everything that I had in the Labyrinth at this moment (I'm not sure that all of this is necessary).

Reflections:
1. Three nameless reflections from the very first battle with Sorrow in the prologue (to save them, just skip six turns) - these reflections are most likely optional for the achievement.
2. Nichtemeron (appears if you save him from the cage in the Cliffs of Sagus).
3. Seriya (appears if you find her in the destroyed house in Sagus Cliffs and give her the cube).
4. Choi (appears if you take her from Inifira’s consciousness while passing through a liquid metal consciousness projector).
5. Inifir (appears after completing the quest "Endless Terror", if the past has not been changed in such a way that he died earlier).
6. Catena’s consciousness (appears if you convince Catena’s artificial intelligence to move into your consciousness in Bloom).
7. Artalio (appears if you feed Artalio to the Maw in Bloom and then, during the quest “Into the Depths,” drag his reflection into your consciousness).
8. Phantom woman and Mistress Anshi (appear in the story after passing the Memovira Fortress).

Measurements:
1. Dimension of the Daughter (quest "Ash Copy" completed).
2. Dimension of the Clock (quest "Torn Out Mind" completed).
3. Dimension of Sorrow (quest "Infection" completed).
4. Dimensions of the Swamp, Village, Oasis and Resonance (appear in the story after passing the Memovira Fortress).

In addition, Rin, whom I sent home, also returned to me (although I don’t think this affects the achievement). And for some period I had a reflection of Erritis in the Labyrinth, but by the time I received the achievement it was no longer there (I’m not sure whether this fact affects the achievement).
