Alterra Corporation

Alterra Logo

Alterra Corporation, also known as Alterra Corp., Alterra TransGov, or simply Alterra, is a Trans-Government that funded the Aurora's mission to construct a phasegate in the Ariadne Arm and owns 9% of phasegates within the galaxy. It appears to be the manufacturer of many machines and tools in-game, as its logo is on many of them.

Despite being legally recognized as a Trans-Gov, Alterra considers itself a corporation. Its corporate structure is made up of an elected board of directors that appoints the overall CEO, appoints the CEOs of major subsidiaries, and makes major economic decisions. Alterra Corporation is made up of millions of smaller companies that are partially or fully owned by Alterra. The corporation makes money off these companies and in return provides expensive services such as starship production. More successful companies' CEOs have a shot at the board of directors. Employees for Alterra are entitled to a one-time share in the Alterra Corporation to afford payments of the Alterra dividend. An exception to these rules are contractors, who are paid by Alterra but are not strictly employees.

Alterra is heavily involved in the arms trade and made substantial amounts of money supplying weaponry to all warring factions during the period known as the Expansion. Their threats to cut off these supplies are said to have been a turning point in the conflict. Today, they are the top supplier to the Trans-System Federation. Alterra does not maintain a standing military, though they do have a police force. Civilian ownership of weapons within Alterra space is strictly controlled, with only the police able to bear arms.

Alterra is rather strict with policies related to resources, even keeping employees "on the clock" after catastrophic accidents. All resources gathered by such employees are company property and Alterra expects to be reimbursed for their full market value after the fact: in the case of Ryley Robinson, this led to a trillion-credit bill.

History and Operations

Although most trans-govs can trace their roots back to earth, Alterra - literally meaning 'by earth' - is the only one brazen enough to take its name. During the Expansion, Alterra supplied arms to all sides, acquiring and housing a vast colonist workforce, and making the transition from manufacturer to corporate state. Alterra's threat to cease trade was one of the turning points in the conflict, bringing about the end of hostilities and the signing of the Charter.

Today Alterra has a ban on all weapons within its borders, although loopholes exist for law enforcement officers and manufacturers / exporters. The corporation has learnt that violence is most profitable when conducted between customers rather than employees.

Free enterprise within Alterra space is encouraged, but competition is tight, and all goods exported offworld must be Alterra branded. Profitable businesses are bought out by the state, owners ascending to the Alterra Board of Directors. Well-known Alterra technologies such as the Cyclops submersible originated with such private enterprises.

Despite superficial similarities to national governments, the corporation's lawyers have always maintained that it has no legal obligation to its 'employees', but voluntarily elects to take on the roles usually served by a democratically elected government. This claim has not yet been tested in Federation courts.
