Remnant

"This civil war tore our planet apart since the assassination of the Federation's leader by the Covenant, an organization consisting of the non-Human species that reside here and are led by the Faunus. But the Federation also has its own problems, many believe that the Federation leader was assassinated by the Kingdom of Xozar, but we do not believe that nor does the Kingdom of Cantis. We've been assisting Xozar against Naven and Noborg in our civil war since."

- King of Hontis Warren Ward to Admiral Annabelle Nakamura on the Remnant Civil War

Remnant was a planet found within the Remnant system of the Arkanis sector located in the Outer Rim Territories. The planet itself was colonized by humans in 853 BBY and found that the Faunus species were the natives. Overtime, other species began to immigrate to the planet, these species included: Twi'leks, Bothans, Duros, Sullustans, Mon Calamari and Quarren. By the time of the Clone Wars, it was discovered by humans that there were a number of Chiss on the planet as well who joined the Covenant in 245 BBY after the assassination of the Remnant Federation leader.

Geography
The number of continents on the planet's surface consisted of eight continents which included: Ablun, Ator, Bokan, Baxont, Dewran, Emith, Facon, and Unai. Ator and Bokan were the two largest continents on the planet and were controlled by the Kingdoms of Hontis, and Naven, respectively.

The Covenant, a non-human organization, controlled a single island near the continent Facon called the "Ancient Haven" which they defended with their small army and navy, and was located in an ocean between Ator and Bokan.

Ablun
Ablun was the continent located near the north-western regions of Remnant, it consisted mostly of frozen ice plains and glaciers that gave wildlife scarce food resources and cold temperatures. It was the third largest continent behind Ator and Bokan, and the neighbor of Bokan, Emith, and Unai. Discoveries made by the Covenant on this continent in 163 BBY gave them belief that Remnant was once controlled by a much larger empire and that the Faunus weren't the primary species native to the planet.

It was also one of the continents covered in snow, the others being Unai and Dewran.

Ator
Ator was the first largest continents located in the southern hemisphere on Remnant, it consisted mainly of forests, mountains, and plains which wildlife had thrived for thousands of years with enough food resources and temperate climates. Being one of the largest continents, it was believed by the Kingdom of Hontis that Ator held many hidden secrets deep within its mountain ranges that remain unexplored due to the terrain.

During the golden age of the Kingdom of Hontis, many cities were built by builders and defended by valleys in between mountains. Hontis also mined from the mountains, claiming large amounts of metal, coal, even rare crystals known as Cestlite, an amber-ruby crystal acting as an energy source, powering Hontis' airships.
