The Lexicon research vessel crashed on the world of MVX-5 in the Chordas System, named Eydan by the indigenous people, and humans were stranded with no outside contact. They found themselves alien visitors on a fertile world with a race and culture they cannot quite understand.
Lawrence "Renz" Banister and Joe Ryan must immerse themselves in Eyan culture and travel across a continent to build an observatory and communications station which will allow the stranded colony to contact their own people off-world, and they must do so without alerting the local government.
