The official unlock condition, without inventing quest coordinates or contribution totals.
Heaven's Threshold opens after the server-wide Cloudstair construction is complete. Version 2.1 makes the restored ascent a shared Hidden Mountain milestone, not a door that one player can open independently before the server reaches the required state.
How the official progression works
- Players repair the broken connections around Hidden Mountain, including water rails that power machinery and irrigate fields.
- The community contributes to rebuilding Cloudstair.
- When the server-wide construction is complete, the restored path opens.
- Players can then climb toward Heaven's Threshold and continue the new region's story.
The dev letter states this sequence at the system level. It does not publish a universal contribution total, a precise menu route, or every prerequisite quest name. Those details can differ by live interface and should not be guessed from the phrase “server-wide effort.”
What waits beyond the gate
Heaven's Threshold is described as a high mountain pass with misty cliffs, ancient ruins, stargazing and mechanical history, and the larger question of the Mohists' failed dream of flight. This is story and location context, not a claim about map-completion rewards.
