Alparians. Daniel's species of people from Alpar Nok. Certain ones have special abilities and Daniel believes them to be the only 'good aliens'. they were called the planet of alien hunters until Firstrike and bombing from Ergent Seth. they call other aliens other than humans and themselves 'outer ones'. they have much in common with humans, near to same atmosphere and life forms, so the Alparians wanted to protect the humans.
