Ciridin (Pronounced SEER-Rih-din) is the fourth planet in the Sigma Draconis System. It is home to one known Forerunner structure.

History Edit

Ciridin's history is long but uneventful for the most part.

Discovery Edit

Ciridin was discovered by a UNSC exploration party in 2412, but was labeled as in a habitable zone since 2056. The ship brought over 30,000 colonists to the planet, where they set up a colony near the Bordagez Sea.

Several continents were mapped out and boundaries drawn. The continents of Zeta, Cey, and Igréga, where identified. A few countries grew and delegates from each would meet in the planet's "capital" city of Angola, the site of the original colony.

Defense Edit

Each country in Ciridin has it's own police force to keep peace within its borders, but outside the borders is the jurisdiction of the UNSC marine forces that keep the peace between nations. Above the planet is an oribital defense grid consisting of three MAC cannons and a station.

Invasion Edit

In early May of 2556, the Covenant separatist force called The True Journey led by Raas 'Zukurramée and Thuzo 'Krarumee invaded the planet in search of ancient forerunner technology.

The True Journey first took out the planet's Orbital Defense Grid, then landed on the surface and began searching for the artifact. Raas found that what he wanted was located within the mountain of Terrus. He landed near the mountain and began excavating it in search of the artifact hidden inside. Meanwhile the rest of the the force set about defeating the marines that were on the planet. Two weeks after the initial invasion, the UNSC Freedom of Spirit arrived with a fleet of several frigates and battleships.

The space battle that ensued resulted in a win by the UNSC, but not before losing a good chunk of their forces.
