Traverse six atmospheric layers: Sand, Mist, Rain, Frost, Clear Skies, and the Stars. Defying gravity as you climb upward, until the tower pierces the heavens and glory reborn. Each tower layer stores its own supplies. With manpower, pipelines, hot-air balloons, even Stronghands hurling cargo skyward...Weave together a seamless vertical network. Reinforce the tower with braces to expand outward. Suspended sky gardens, lattice-like aerial platforms, defy gravity for boundless creations in your celestial city. Forge Ritual Platforms, where the faith of your Towertizens gathers into a force that can summon wind and rain. Fulfill their wishes, and they will gift you their most precious gems. As the tower ascends, Towertizens will endure trials of faith and disaster. Light Miracle Towers as beacons of hope that bolster morale, efficiency, and pacify the calamities.
