Eras and Features=

ORION
The ORION Era (2490-2517) ''covers the end of the 25th Century and the start of the 26th. It is a time of great change for mankind as the threat of rebellion looms overhead, and largely covers the exploits of the men and women of the ORION Project from their first successful operations to the tragedies and failures that ended it, eventually leading up to the inception of the SPARTAN-II Program and the offshoot that gave this universe its name.''

Covenant
A major part of the Sigmaverse, the Covenant Era (2517-2553) ''covers nearly forty years, largely focusing on the devastating Human-Covenant War and the battles that occurred during this period. As most of Halo canon takes place here, Sigmaverse characters will take part in a number of well-known events, from the Harvest Campaign to the Battle of Earth. This era also has the biggest focus on the original Sigma Team, a group of nine SPARTAN-II's who fought to defend humanity during this conflict.''

Rebellion
The Rebellion Era (2553 onwards) is the latest period of history in the Sigmaverse and covers the numerous conflicts following the Human-Covenant War. While the immediate threat of the Covenant has passed, this era sees the emergence of several new factions as the galaxy becomes a much more dangerous place, leading up to the climactic war against the Created.
