Route (5 sub-chapters)

Paradise — beach + forest, the densest stretch. Spawn on the beach: turn around for the turtle achievement, and check the wrecked boat (Resonance Point). The Conch Shell sits in the seaside cave; after the green door, swing across the gap for the Play Onyx. Boost Leni onto the ledge, push the log, and the Golden Cup waits at the far beach's dead end.
Vestiges — the large statue area. Jump the gap to the ruins for the Heroic Plaque; grapnel down the fence and go up the right stairs for the Strategy Game (Arm Band #1 drops through the broken floor below it).
Rats in a Barrel — inside the buildings: Beads #2 at the bottom after sliding in; Bracelet #2 in the left room where Leni needs help with the door.
On the Run — Seal #1, after reuniting with Leni and sliding down, past the fence.
The start of the trials — cross the river into the temple and solve the lens platform puzzle to descend.

⚠️ Missable Achievement: Sea You Later

Right after spawning on the beach, turn around and walk along the shoreline until you see the turtle; wait for the dialogue to end and the achievement pops. The main path faces the opposite way, so it's easy to walk straight past.

Puzzle: Three-Latch Platform (end of the chapter)

The temple platform is held by three latches. Chain light through the lenses onto three golden dials to release them:

Interact with the sphere pedestal in the centre to activate the light.
Latch 1: use the lens on the right to shine light straight onto the golden dial ahead.
Latch 2: rotate the same lens left so the beam hits the lens on the platform left of the pedestal — walk over to that lens and aim it at the dial on the left wall.
Latch 3: in the northeast corner, find the broken lens on the ground and let Leni hold it up; return to the previous lens and shine into it — the beam bounces onto the final dial.
Insert the sphere into the centre pedestal — the platform descends and the chapter ends.

Fixed in Update 1.003 (Oct 6, 2026): a bug where Leni's lens interaction could not trigger in this puzzle was fixed in the October 6 Bug Fix Update — update your game if you're stuck here.

Resonance Points (9) — Locations

#	Where
1	Spawn beach — wrecked boat, opposite the main path
2	After climbing the back-left cliffs, below the slope
3	Jump the gap to the ruins — tree stump on the sea cliffs
4	Tallest ruin in the corner — grapple up to the viewing platform
5	Through the abandoned camp, on the right before the ladder
6	Big open area in Vestiges — drop below the wooden platform
7	Lower ruins right corner (by the Beads #2 charm)
8	Big statue area — up the left hill, in a basket
9	After rafting across the water, in the temple by a broken statue head

Points 1 and 2 are the easy misses — both sit off the main path. See the Ch3 Resonance Points page for the full walkthrough.

FAQ

Q: How do you solve the Chapter 3 lens puzzle? A: Activate the sphere pedestal in the centre, then chain light through the lenses onto three golden dials — dial 1 straight ahead from the right lens, dial 2 by rotating that lens left into the platform lens and aiming at the left wall, dial 3 by shining into the broken lens (Leni holds it) in the northeast corner. Insert the sphere and the platform descends.

Q: Is the Sea You Later turtle achievement missable? A: Yes. Right after spawning on the beach, turn around and walk along the shoreline to the turtle; wait for the dialogue to end and the achievement pops. The main path faces the other way, so it's easy to walk straight past.

Q: How many collectibles are in Chapter 3? A: 19 — 6 artefacts, 4 charms and 9 Resonance Points. No blade in this chapter.
