Madrigal

Madrigal was a UNSC colony world in the 23 Librae system. It was the closest world to Harvest in 2525. The colony was glassed by the Covenant, but the survivors fled to the gas giant of Hesiod, where they settled into the asteroid belt.

Behind the Scenes
Madrigal was a city in Bungie's Myth series, as well in the Siege of Madrigal, a music piece from Marathon, and as such is a nod to two separate Bungie-made series.
