Dorin gas was a major constituent in Dorin's atmosphere
On the planet of Dorin, the air was primarily composed of two gases, one of which was Dorin gas, with helium being the other. For the Kel Dors species, it played a vital role, analogous to how oxygen is crucial for other life forms such as humans. In contrast, Kel Dors found oxygen to be a poisonous substance.
