Knowledge Islands Enter Arcadia
Menu
Arcadia at dusk, seen from high above. The Capital crowns the hilltop, the Observatory's dome stands on the heights to the right and a lighthouse on the left headland, with a great tree at the heart of the forest between them. Streams fall in waterfalls towards the Port on the shore below: an airship at its mooring mast, docks, a rail shed and moored ships. Sailing ships follow a dotted sea lane past small islets, distant islands lie under the sunset, and cloud closes the right-hand edge.

The legend
