Zonama Sekot (Ferroan for "World of Body and Mind") and labelled by Chiss surveys as M-Eighteen, was a living rogue planet in the Unknown Regions. Zonama was the planet itself, while Sekot was the living organism. It became the adopted homeworld of the extra-galactic Yuuzhan Vong after the end of their war of conquest of the galaxy.
Zonama Sekot was born from a seed of Yuuzhan'tar, the original living sentient homeworld of the Yuuzhan Vong which had been destroyed during the eons of conflict in a distant galaxy. Zonama Sekot was once in the Tingel Arm of the Outer Rim Territories before disappearing into the Unknown Regions.
Zonama Sekot was unique from other worlds. Its north polar region, a spot of pearl white was surrounded by an entire hemisphere of tropical jungles. Its southern hemisphere was covered with impenetrable silvery clouds. Along the equator there were several rivers, lakes, and small seas. The edge of the southern hemisphere was also covered by elegant wisps of wind which frequently broke free to form spinning storms.
Zonama Sekot was the seed of the original Yuuzhan Vong homeworld, Yuuzhan'tar, which had been destroyed during the Cremlevian War.
Zonama Sekot's first settlers were black-haired humanoid Ferroan colonists and red-skinned Langhesi colonists, and the living world was ruled by Magisters. The Ferroans were believers in the Potentium view of the Force. The Langhesi and Ferroans settled the planet in 89 BBY.

During the time of the Galactic Republic, Zonama Sekot was rumored to be home to the fastest ships in the galaxy. Jedi Knight Obi-Wan Kenobi and his Padawan, Anakin Skywalker, traveled there to find fellow Jedi Vergere and to purchase one of the planet's living ships. Anakin bonded with a record twelve seed-partners, Obi-Wan bonded with an additional three. While Zonama Sekot was under attack from the Yuuzhan Vong (32 BBY–30 BBY), it was able to defeat them. Later Wilhuff Tarkin, then a Republic political leader and security force commander, declared war on the living world and attacked it in 29 BBY. Zonama Sekot unveiled its hyperdrive system, which had been built by the Langhesi, and escaped into the Unknown Regions.
In the following years, stories of the "rogue planet" that had once made living ships circulated among many in the Outer Rim.
Many years later during the Yuuzhan Vong War, Luke Skywalker, Mara Jade Skywalker, Jacen Solo, R2-D2, and several other Jedi traveled to Zonama Sekot, which harbored the long forgotten secrets of the galaxy's invaders. Recognizing a glimmer of Anakin Skywalker in Luke and Jacen, Sekot allowed them to land and tested them. Sekot offered to destroy the Yuuzhan Vong entirely, but both Luke and Jacen refused. Nevertheless, Sekot decided to help them, in another way. Later, Nom Anor, disguised as Yu'shaa, the leader of the underground Jeedai heretics, tried without success to destroy the living world.
Zonama Sekot traveled to Yuuzhan Vong-held Coruscant, which had been renamed Yuuzhan'tar, and forged a peace between the Yuuzhan Vong and the Galactic Alliance. Converted and surrendered Yuuzhan Vong came to call Zonama home, and a number of communities were established. One such village was La'okio, created as an experiment to break down the walls dividing the Yuuzhan Vong castes by grouping the beings into mixed groups.
Reh'mwa, a leader of the Bothan ar'krai against the Yuuzhan Vong, provisioned the Avengeance for searching for Zonama Sekot in the Unknown Regions. After the end of the war, Luke Skywalker held a meeting on the planet to explain the role of the Jedi in the post-war galaxy.
At the start of the Sith–Imperial War, it retreated further into the Unknown Regions, stranding the Yuuzhan Vong who remained in the galaxy as part of the Ossus Project. As of 130 ABY it was located in the Unknown Regions, roughly halfway between Lwhekk and Lehon.
In the original outline of The New Jedi Order: Force Heretic III: Reunion, Zonama Sekot was going to have a young, sentient moon termed "Zonama X", which would have convinced its parent world to join the war against the Yuuzhan Vong.
