World

Discover the various settings found in the novel on this page. Better known locations such as Earth, Mars, Jupiter, Neptune, and others are not discussed.

Artemis Water Treatment Plant

A facility on Europa responsible for pumping water up from the moon's underground ocean, purifying the water, and distributing the water to the rest of the Jovian system.

Callisto

Jupiter's eighth moon in terms of distance from the planet and second larget moon after Ganymede. Callisto is home to multiple colonies, including New Galilei, and Base HOPE, the main U.N. military installation in the Jovian system. Callisto was the first moon settled in the Jovian system. The moon's distance from Jupiter minimized the amount of harmful radiation reaching the surface. As force fields became capable of radiation shielding, moons closer to the gas giant such as Ganymede and Europa were settled.

Ceres

The largest asteroid in the asteroid belt between Mars and Jupiter. Ceres is home to multiple human mining settlements.

Europa

Jupiter's sixth moon in terms of distance from the planet and third larget moon after Ganymede. Europa is home to the Artemis Water Treatment plant as well as multiple other colonies.

Huygens colony

The sole human settlement on Titan and in the Saturnian system.

Jovian System

The planet Jupiter, its rings, its moons, and the elements of human civilization found there. The Galilean moons of the Jovian system are home to several million people. Scientifically speaking, the Jovian system extends all the way out until the gas giant's gravity becomes negligible.

Kuiper Belt

The solar system's second asteroid belt. The Kuiper belt extends from the orbit of Neptune to the edge of the solar system and is less densely packed than the belt between Mars and Jupiter. Pluto is a Kuiper belt object (a very large asteroid) and is thus a dwarf planet, not a regular planet. The Kuiper belt is home to hundreds of dwarf planets, some bigger than Pluto (Eris, for example). Even in the 23rd century, humans have yet to set foot on any of the Kuiper belt worlds because they're so far away. But the phase drive promises to change that.

Luna

The proper name of Earth's moon. Centuries ago, people referred to Luna as The Moon because it was the only moon that mattered or that humans knew. As humankind branched out into the solar system and settled many different moons, the term "the moon" became ambiguous. Thus, the people of the 23rd century refer to Earth's moon by its actual name, Luna. Relatively speaking, Luna is heavily populated in the 23rd century.

Nereid

Neptune's eighth moon, the site of an important skirmish.

Neso

Neptune's thirteenth moon.

New Galilei

The first and largest colony settled on Callisto and in the Jovian system. Named after the astronomer Galileo Galilei as well as the Galileo probe sent by NASA to study Jupiter and its moons in the late 20th century.

NISS

The New International Space Station. Built in the early 23rd century, NISS is a rotating commercial space station in Earth orbit. The station is home to over 20,000 people.

Red Rock City

One of the larger colonies of Mars near Valles Marineris, a canyon bigger and deeper than The Grand Canyon on Earth.

Themisto

Jupiter's ninth moon. The moon plays an important role when an unknown enemy force attacks Callisto.

Titan

Saturn's largest moon. The moon is home to Huygens colony, the only human settlement in the Saturnian system. Titan's atmosphere is extremely thick, and its terrain looks similar to Earth's, although the rivers flow with liquid methane and the mountains are made of ice. Titan and the Saturnian system are the farthest humans have explored and settled with the exception of the expedition to Triton that was never heard from again. Don't confuse Titan with Triton.

Triton

Neptune's largest moon. The U.N. sent an expedition to this moon that was never heard from again. No human has ventured out to the Neptunian system since the expedition was lost. Don't confuse Triton with Titan.

Trojans / Trojan Asteroids

A group of asteroids that sit within Jupiter's orbit at a lagrange point and orbit the sun along with the planet. The U.N. constructs spacecraft carriers within the Trojans by using the raw materials within the asteroids.
