Hira

Hira was an Interstellar Coalition colony settled just after the Xindi Conflict.

During the Guardian Conflict of 2157, the planet was among 27 Coalition frontier worlds that suffered a biological weapon attack by the rogue Cylon group, the Guardians, via their flagship squadron, the Crimson Elite.

The planet suffered heavy causalities and had to be evacuated for over a year until such time as the viral infection could subside and colonists could return. Following the conflict, the planets attacked by the Guardians became known as The 27 Dead.
