Rasa was a male Edemian who lived in the 24th century.

In 2369, Rasa came to Deep Space 9 with his parents Mas Marko and Azira, two missionaries of K'olkr. Julian Bashir discovered that Rasa was suffering from panoria, which Azira allowed Bashir to treat him for, against the wishes of her husband. Despite Rasa being cured by Bashir's tricyclidine treatments, Marko disowned his wife and son. (DS9 novel: The Siege)
