This territory served as a special development zone jointly constructed by the Entente, the Republic and the Union under the agreement. Nominally, the Joint Development Territory was also part of the Republic's territory, possessing a high degree of autonomy similar to the provinces within the Republic. However, its administrator was not the provincial council of other provinces, but rather the Joint Development Territory Management Committee composed of Earthlings.

In front of the Ruvilian people, both factions were eager to present themselves as a united and cooperative force of "Earthlings." Building an Earth-style industrial system from scratch on an alien planet was an extremely difficult task and the Earthlings of the United Territory, in most cases, The earthling were indeed able to transcend factional, racial and ideological prejudices and work together harmoniously. This also meant that the Ruvilian people generally could not clearly distinguish between Entent members and Union members, nor could they discern any differences in their industrial systems and ideologies.

Relying on the advanced technology and talent generously invested by the two major camps, as well as the local manpower and resources of the Planet Nox, the joint development Region was built into the main landing site for receiving interstellar deliveries from Earth, The city Became the only space launch center on the planet Nox and the most sophisticated and high-tech industrial center on the planet Nox.
