Summary
Sirti-nei-Plex is a small and gracile Arcadian who serves as an Engineering Officer aboard the USS Redding.
The Arcadians are a species of delicate amphibious sentient beings who have been in the Federation for more than 100 years. Like his compatriots, Sirti is a pacifist and a skilled engineer. He can work both in water and air environments, and needs to spend some time in both each day to maintain his metabolic equilibrium.
His species is short-lived (they rarely live to 60 years) but they are very precocious; Sirti is therefore the youngest member of the crew.
He is patient and shy, and speaks with a nasal, high-pitched voice.
