Based on an overseas player guide, this lays out which Spire or quest unlocks each of the 40 Abyss Restoration locations. Each restored Abyss gives 1 Abyss Artifact and a sky fast-travel point.
Total: 40 locations
Auto-restore in Chapter 1: 2 (first cluster of 4 including follow-ups)
Elemental skills: Lightning, Frost, Flame, Wind (4 Abysses)
Final one: Dimensional Bonds, 10 Artifacts
Achievement: Conqueror of the Abysses
How Abyss Restoration works
Abysses are the floating islands you see on the sky map. Each has a Skybridge and one environmental puzzle: grab the button or pillar with Axiom Force and the island connects. Two Abysses repair themselves in Chapter 1, and most of the rest sit in clusters with a single entry Spire that you must open first. Restoring all 40 unlocks the Conqueror of the Abysses trophy. Abyss names here are English names as reported by players; no official Korean names were confirmed apart from three.
Clusters by unlocking Spire
Chapter 1 opening cluster (4): Ethereal Pathway, Axiom Archive, Root's End, Precipice of Truth.
Spire of Clockwork (5): Riddle Square, Origin of Thoughts, Forgotten Altar, Disconnected Truth, Ether Fragment.
Spire of Frost (4): Tomb of Perdition, Passage of Malice, Desert Fragment, Cradle of Truth.
Jijeong Temple Pagoda (3): Ascetic's Rest, Path of Serpents, Crossroads of Uncertainty. Bowsprit Cape between them is a connector puzzle that is not one of the 40.
Spire of Soaring / Chapter 5 (3): Crow's Nest, Crescent Skybridge, Monolith Crown.
Spire of Ringing Truth (8): Skyloop Bridge, Ether Rest, Sanctorum of Darkness, Twisted Thicketway (boss fight needed), Path of Trials, Frostbitten Paradise, Tree of Slumber, Loop of Life.

Spire of the Sun (4): Nest of Valor, Sanctum of Transcendence, Throne of Truth, Dimensional Labyrinth. Opens after Chapter 9.
Spire of Insight (2): Roots of Truth and Chaos Forest, which starts with Nature's Grasp on the wall.
Four Abysses that grant elemental skills
Courtyard of Precision (Spire of the Stars cluster): Lightning
Path of Trials (Spire of Ringing Truth cluster): Frost
Tree of Slumber (Spire of Ringing Truth cluster): Flame
Riddle Square (Spire of Clockwork cluster): Storm Veil, which adds Wind to your attacks
These help with later puzzles and fights, so they are worth doing early.
The final Abyss: Dimensional Bonds
The 40th Abyss appears only after you finish the main story and the other 39 Abysses. Every other Abyss gives 1 Abyss Artifact, but this one pays out 10 at once. A short scene shows every connection point linking to the center, and it works as the closest thing to a final boss for the exploration side.
