Thelembule

Thelembule is a vine-choked swampy core world deep within the heart of UPA controlled space. It served as one of the first major interstellar population centers of humanity, and has a history of intense strife and warfare. One of the first major planetside battles of the Writ-Human war occurred on its surface, and it played a key strategic role throughout the conflict. Tragedies throughout the planet's history have earned it an unlucky reputation and the nickname of the Snake's Eye.

Geography
Thelembule is a massive bog planet roughly the size of Neptune. Its sheer size translates into huge swathes of unpopulated and mysterious swamps, interspersed with fishing towns and sprawling megacities. Of the planet's surface 87% of its land is uninhabitable due to unstable ground or choking vegetation. It has one ocean called the Mausalean Sea.

Three moons orbit Thelembule. The largest is Grootslang, a planet habitable only one month of the year due to an orbit that puts it in intermittent cycles of wildly hot and wildly cold temperatures. Its two smaller moons, Bunn & Yip orbit Grootslang, and are otherwise entirely unnoteworthy.

Population
Of the 342 million people that live on Thelembule, a vast majority are military brats. This is due to the fact that the planet is still littered with countless army bases from the Writ war, hidden away under foliage or in bunkers deep within the swamps.
