Madrigal is known for its immense trees, many of which can reach over 400-meters in height and also lacking almost most forms of terrestrial animal life. The colony was founded by a Capecchi group of settlers, the Asimov, who modified themselves to survive on a vegeterian lifestyle.
Currently the Asimov of Madrigal are the large group of Capecchi in the Republic.
The planet formerly was an Earth Federation colony that broke away during the Sol Gamma Wave in 2601, forming what commonly became known as the Western Territories. It later was conquered by the Republic during the Annexation of the Western Territories in 2743, the Republic's annexation of the 27 independent colony worlds that dominated the space to its galactic west.
The planet rebelled during the Lovejoy Revolution and broke away in May 3073 during the Cessation of the Western Territories. It allied with the other rebelling worlds, forming the Western Confederation of Independent Worlds.
The planet is named for Madrigal, the name of a form of poetry, the exact nature of which has never been decided in English.
