Artificial Aerostat Flight is Invented

Technological achievement

Vexan Zin, a Rostran tinkerer, observes that lanterns sent into the air during his island's annual summer candle festival fly because of the hot air inside of them. He builds a scaled-up version of a flying lantern with a harness for one passenger. This is the first artificial aerostat in the Manifold, an invention which will not yet be replicated by Voxelians for 135 years, though the Verdials had a few rare "sporeships" made from natural materials since 7500 or earlier.
