ARGOANS

Home Planet:

Argo/Aqua
   Class M

Atmosphere:

 Oxygen, Carbon Dioxide

Life Forms:

Water breathing Humanoids

Language:

Aquan

History:

 Once their civilization lived on the land, just like Terrans. A planet-wide catastrophe caused virtually all the land to sink under the waves. Aquan scientists developed a serum that would change their race permanently into water breathers, and administered it to all the population in time to save the civilization. This was hundreds, if not thousands of years ago in Aquan history. Now they are all at home in the sea, and blame air breathers (in essence, their ancestors) for the planetary calamity that overtook them.
  The Federation has had only one contact with Argoans, and have placed a quarantine on the world to protect both the citizens of the world from unwanted contact from air breathers and to protect their world from unscrupulous traders wishing to capitalize on the Argoan's advanced scientific techniques. The Aquans, on their part, are quite glad not to have any unnecessary contact from air breathers
