Hearth

Hearth is the sole major moon of the planet Haven, the fourth planet in the Hope System within the Ambrosia Galaxy. Classified as an S-Class world, Hearth has undergone significant transformation from a barren satellite to a thriving Ecumenopolis.

Overview

Hearth is an average-sized Selena-class moon, characterized by a rugged terrain of hills, mountains, craters, and canyons. Composed almost entirely of rock and dirt, the moon contains minimal precious metals. Sparse iron deposits are scattered across its surface, with minor traces of cadmium also present.

Originally, Hearth was the second major moon of [[Haven]], following its larger counterpart, Harmony. However, Harmony eventually drifted into Haven’s Roche limit and was torn apart, forming the Rings of Harmony, a vast ring system encircling the planet.

Today, Hearth has evolved into a fully developed Ecumenopolis, where its entire surface is covered by a sprawling megacity. It boasts the largest human population of any Ecumenopolis in the Ambrosia Galaxy, serving as a crucial hub of civilization.

History

Hearth formed alongside its parent planet, Haven, and its former sister moon, Harmony, around 4.5 billion BCE. Upon formation, Hearth initially followed a retrograde orbit, moving opposite to Harmony’s prograde orbit. This resulted in an extended period of gravitational interactions between the two moons, culminating in Harmony's gradual descent toward Haven. Ultimately, Harmony entered the planet’s Roche limit around 3.77 billion BCE, leading to its fragmentation and the creation of Haven’s ring system.

The Havenites became the first known Ambrosian civilization to explore Hearth, successfully launching a manned mission to the moon in 2.49 billion BCE. Continuous expeditions followed throughout the era, leading to the establishment of a permanent, self-sustaining colony by 2.489 billion BCE. Over the next four millennia, additional Havenite settlements expanded across Hearth, steadily urbanizing its surface. By 1.64 billion BCE, Hearth had fully transformed into a bustling Ecumenopolis, marking one of the most significant milestones in its history.
