Karma is the fourth planet in the Aluxia system, and is the only known astronomical object to harbor native biological life, and one of three in its solar system to have liquid water. Radiometric dating places the approximate age of Karma at roughly 4.5 Billion YBP. Karma's gravitational field interacts with a number of other astronomical objects, chiefly its star, Aluxia, as well as its two moons, named [MOON 1] and [MOON 2], respectively.

Owing to its axial tilt, Karma experiences distinct seasons. Its gravitational interactions with its moons, primarily its larger one [MOON], stabilizes Karma's axis, and slowly has slowed its rotational period. Karma is the densest planet in the Aluxia System and the largest of the four rocky planets.

Karma's outer layer, known as the lithosphere, is composed of numerous distinct tectonic plates, which migrate across the surface of the planet over the course of millions of years. Roughly [LAND PERCENTAGE] is composed of landmasses including continents and islands. The vast majority of the world at [WATER PERCENTAGE] is covered by water, mostly by salt water oceans, but also with sources of fresh water, including lakes, rivers, and by ice across much of the planet's polar regions, and elsewhere in the form of glaciers. The planet's interiors are more geologically dynamic, characterized by a solid iron inner core, liquid outer core which produces the planet's magnetic field, and a convecting mantle which controls the process of plate tectonics.

The first billion years of the planet's history saw the arrival of biological life in its oceans, leading to increasingly complex organisms. Some estimates place the earliest appearance of life at approximately 4.1 Billion YBP. Karma's unique set of astronomical characteristics, including its distance from its star, its physical geography, and others, have allowed for the proliferation of increasingly sophisticated forms of life, many of which have not been described and recorded. The most notable is the genus homo, specifically homo sapiens sapiens. Humans are the only known form of complex life which has formed complex social structures characterized by abstract thought, religion, philosophy, and increasingly complex forms of technology, alongside an expanding accumulation of scientific knowledge.
