Osmium Court

The Osmium Court was a floating continental fragment which rested upon an ocean within the gas giant planet Fundament. It was a remnant of an ancient cataclysm when the Krill homeworld crashed into Fundament, after which it served as the new home of the Krill species.

Overview
The Osmium Court was ruled by a King who sired many broods of children, notably Aurash, Sathona, and Xi Ro. Taox, a neutered Mother designed great engines to navigate the treacherous seas of Fundament; when they were active everyone needed to stay far from the edge or exercise extreme caution. It possessed a lightning farm, presumably to generate power for the engines, and an orrery to study the movements of Fundament's fifty-two moons.

History
The Osmium Court was betrayed by Taox—who feared both that her King was abandoning his people and that his daughters were unfit to govern—to the rival Helium Drinkers and Court. It was later retaken by the Worm-empowered Hive led by Auryx and his sisters, and presumably destroyed and then abandoned when they ascended to attack the Ammonite civilization.

Trivia

 * The Krill homeworld may have been one of the moons of Fundament, or at least local to the same planetary system. If Aurash is to be believed, the Krill deliberately manipulated their world to crash in order to hide.
 * According to a vision imparted by the Relic on Mars using Savathûn's ancient, calcified Worm familiar, the Osmium Court closely resembles the island found at the center of the lake atop Savathûn's massive bowl-shaped fortress in her Throne World. Whether this is merely symbolism within the context of the vision or evidence that Savathûn designed the island after her ancestral home is unknown.
