Originally uplifted for use in the Martian Terraforming Project as surveyors and explorers, tasked with keeping maps and surveys up to date with the rapidly shifting Martian landscape over the course of the project. Fatality rates were high as the corvidae were treated as expendable, and this engendered a lasting suspicion and dislike of the Solar government amongst the corvid population. The corvid 'home world' is Saturn's seventh moon, Hyperion, and the formal citizenship term for most natural-born corvidae is 'Hyperionian'. Corvid naming conventions are a chosen name followed by the species of the person, followed by the location they were hatched.
