Alterra Corporation

Chinese Trans-Gov
This Chinese Trans-Gov is mentioned in the Mongolian Independent States profile in Subnautica, though it remains unnamed. The Mongolian Independent States originally existed as colonies on the far reaches of the Chinese Territories. As the warring times of the Expansion came to a close, these outer colonies were more or less abandoned, leading them to declare their independence as the Mongolian Independent States.
The Chinese Potato Plant was created in the Chinese Territories.
Czech-Consortium
The Czech-Consortium is listed as a Trans-Gov, though specific details are limited in available records.
Ikweta-Mondragon
Ikweta-Mondragon is a Trans-Gov mentioned exclusively in the profile of Phoebe Grammaticas, who was a citizen of Ikweta-Mondragon prior to immigrating to Alterra.
"Ikweta" is a Swahili transliteration of the English word "Equator", whilst Mondragon originates from the Spanish town "Mondragón" and the real-world Mondragon Corporation. It is likely that Ikweta-Mondragon traces its lineage back to various parts of Southern Europe and Africa.
Mongolian Independent States
The Mongolian Independent States are a former colony of the Chinese Trans-Gov that declared independence after being abandoned during the end of the Expansion era.

Sol is mentioned in Subnautica: Below Zero as the owners of the crashed Mercury II vessel. Based on dialogue, the Trans-Gov appears to descend culturally from Anatolian, Grecian, and Arabic cultures. Little else is known of Sol.
United Trans-States
