Chi Rho was a human Inner Colony planet in the Ectanus 45 system, governed by the Unified Earth Government. Orbited by the colonized moon of Eiro, Chi Rho was one of the worlds said to separate the Inner Colonies from the Outer Colonies. A large blue planet, Chi Rho had an Earth-like surface and its largest continent was home to hundreds of millions, though not as developed and comparatively smaller to the colonies in the Sol and Epsilon Eridani systems. The planet is now uninhabited in the wake of the Human-Covenant War.

History

In 2535, during the Human-Covenant War, following the loss of most of the Outer Colonies, refugees had started flooding the planet and all available space was being used for victory gardens and refugee camps. Vice Admiral Jean Mawikizi resolved to make a stand against the Covenant on Chi Rho, digging in deep within the planet's crust to survive a glassing attack, forcing the Covenant to come down and flush them out man-to-man.

At some point during the Covenant War, a battle evidently occurred on or near Chi Rho. By the war's end, the planet was uninhabited though seemingly unglassed, with the remains of the downed Halcyon-class light cruiser UNSC Roman Blue resting on Eiro. By 2557, Chi Rho was still uninhabited, though Eiro still remained lightly populated.

Trivia

"Chi Rho (XP)" was a symbol used by the early Christian church to abbreviate the name of Jesus Christ. It is formed from the first two letters of the original Greek title Christos:ΧΡΙΣΤΟΣ.
