Jacinto

"Even after being under siege for four years, Jacinto remained one of the most economically successful colonies following the war. It's nearly unmatched when compared to other colonies. It's a wonder how it became so powerful and a major driving force of humanity's economy."

The Collective Commonwealth of Jacinto, (CCJ) usually referred to as Jacinto is one of humanity's most successful "boom-worlds", as vast untapped resources and fertile land for agriculture provided the colonist with the necessary capabilities for rapid growth, and to develop into a major economic hub for the Unified Earth Government well into the 2550s. Jacinto is the third planet in its solar system and did not require terraforming as the planet was already suitable to human habitation as well as having an array of native and exotic lifeforms.

Following the end of the war, Jacinto would establish an inter-species trading network between the humans, Sangheili, Unggoy, Kig-Yar and Yonhet. However, cross-species tensions still remained high on the colony as Jacinto was besieged by Covenant forces in 2549 with it finally being lifted in 2553. The Covenant had sent a small but formidable invasion force to Jacinto to capture the planet for its valuable Helium-3 and Platinum deposits. The resulting invasion lasted for four years with sustained fighting on the surface and in orbit.
