Sirian (Proof)

The Sirians are a sapient race of ovoid creatures native to the interior of the stars of the Sirius System. Their biology is similar to that of the Solarians and other stellar species, with a "skin" made out of dense electron fields and an interior core of neutronium. They differ from the Solarians for being longer and narrower, and possessing pyramidal "horns" of neutronium projecting through the "skin" at their tips.
