The short answer
Four pink crystals surround one mirror on the larger right island: two above it, one to its right and one below-left. The trader also starts there, and a fixed rock caps the island’s southern tip. Across the wide gap, the left exit island has four more fixed rocks around its northern and eastern edges and southwest corner.

Hint 1 — a direction to explore Reveal solution / story details
A reflected crystal can land in water or on a crossing tile you have already made. Think about where the trader must land to push the next crystal farther left.

Hint 2 — the useful arrangement Reveal solution / story details
Use the mirror to send the crystals into one crossing row. Leave enough room to reflect the trader immediately right of a standing crystal, then push it left into the next gap.

- Make space around the mirror by moving two crystals down the right island’s southern column. Move the mirror up and left until its leftward reflection line runs through the water toward the exit island (9:24).
- Reflect two crystals into the water along that line. Two submerged crossing tiles are visible at 9:29.
- Use reflection to reach those tiles behind another crystal. Push that crystal left into the next water gap. The crossing has three submerged crystals by 9:39.
- Return through the mirror for the last crystal on the right island. Bring it into the mirror’s southern line and reflect it onto the crossing row. At 9:45 it stands between previously submerged outer tiles.
- Stand farther south on the right island so your reflected image is immediately right of the standing crystal. Transfer there (9:46–9:47), then push the crystal left across the existing tiles and into the last water gap beside the exit island (9:48).
- Walk onto the island, around the fixed rock at its edge, and onto the exit. The trader occupies it at 9:49.5; four pink crystals form the completed crossing.
