The water world was nearly all blue, with the tiniest of brown and red specks denoting islands. The oceans varied from dark to light, as the sun reflected off depths and shallows. There were larger landmasses, but at the time, those were on the back side of the planet, and all the crew of Kamahele could see was blue.

The navigator, or kilo hoku, of their predominantly Polynesian crew wanted to name the planet Wehe ka pe’a, Hawaiian for “close the sail.” He was overruled by the Captain. “The world is blue. Everyone knows it’s blue. We will call it by its name, Bl—”

“Azure.” The interruption came from Makeo Johnston, the colony administrator, who would later become mayor and then governor of the nascent colony.

“—ue…okay, Azure it is.”

"The planet was eighty-percent ocean, with a few large island-continents midway between Greenland and Australia in size.The continents, numerous islands, and archipelagos were arranged in a circle in one hemisphere, the result of some cataclysm in the distant past. The result was some truly spectacular mountain ranges and seamounts, and considerable tectonic activity surrounding a sea that was largely protected from extremes of weather by the blocking effects of the islands. As a result, most of the population of Azure settled in the “Eastern” Hemisphere, where dry land was abundant, and the seas were well-suited to mariculture and sea-farming. The “Western” Hemisphere was stormy, with few safe anchors, but some truly spectacular forms of aquatic life."
"Azure was a tropical dream, but rather than becoming a vacation paradise, it was a simple colony of land and sea farming. Earth’s sea-life adapted easily to the shallow Lepo Sea, with its low salinity—about two-thirds that of Earth oceans—and Earth plants grew well in the coastal plains. The continental interiors were hot and dry, and the windward, outward-facing coasts were stormy and difficult to navigate..."
The Lepo Sea
"...within the protective circle of islands, Humans could live, and even thrive. There was no need to venture far from Landing City or the islands to either side of the main continent of Ho’opa’a."
