History and Specifics[]
The surface of Ceron consisted of numerous large islands encircled by tempestuous seas. High algae concentrations impart a brown hue to the oceans. Federation colonists have adapted to utilize the algae as both a food source and a fertilizer for crops. (ST video game: Star Trek Online: Ceron system lore)
