Angkor Wat

One of the eighteen Astral Bridges, and Samson's guardian post — on the spring equinox the sun rises to sit exactly over the temple's central tower when viewed from the western entrance, a single sightline the whole complex was built around.

In the game — the Equinox Tower task: overgrowth is blocking the western sightline to the central tower. Clear the exact line of sight before the equinox sunrise passes unwitnessed. Completing it adds Samson to your portfolio and unlocks permanent fast travel to Angkor Wat.
