Bedrosian archaeologist charged with unburying the Stargate. Nyan considered himself a Bedrosian loyalist, but a scientist first and foremost. Discovering the Optrican theory was correct, he was disappointed but still pleased to find truth, unlike the military leaders in his government. Still, he prayed to Nefertum for guidance.
Nyan vouched for SG-1 and their struggle to return to Earth, remaining with Teal'c and repairing his blinded eyes with an optic nerve regenerator. Shortly after, he helped lay down cover fire for SG-1, and was beckoned to return with them to Earth through the open Stargate.
Back on Earth, Nyan was offered a position to become Daniel Jackson's research assistant. Since that arrangement he has not been seen, but his services and expertise as a Bedrosian are undoubtedly becoming useful elsewhere.
New Ground - Nyan and Mallin unbury the Stargate on their world, discovering that it is the legendary Optrican gateway.
