The Sarpeidons are a
race by now exctinct. In Stellar Data 5943.7 the sun of Sarpeidon, Beta Niobis, blowned up
into nova. All the Sarpeidons did refugee in the past through a machine called Atavachron,
that allows the journey bashful in the time. The Sarpeidon possessed an extraordinarily
advanced culture, and an enormous library, but they didn't know space travel. All their
knowledges went lost after the explosion of the sun in nova.
