Terceira

Terceira is a colony world of the United Earth Government located in an undisclosed star system. Following the Human-Covenant War, the Spartans were deployed to the colony to suppress the local insurrection. A number of MJOLNIR Powered Assault Armor permutations saw use among the Spartan forces present during the operation, including inner-plated forearm guards and the Oceanic variant.

Trivia
The colony is presumably named after an island located in the Atlantic Ocean; it is part of the Azores archipelago, a Portuguese autonomous region on Earth.
