Polar stratospheric clouds (PSCs), also known as nacreous clouds (/ˈneɪkriəs/, from nacre, or mother of pearl, due to its iridescence), are clouds in the winter polar stratosphere at altitudes of 15,000–25,000 m (49,000–82,000 ft). They are best observed during civil twilight, when the Sun is between 1 and 6 degrees below the horizon, as well as in winter and in more northerly latitudes.They are implicated in the formation of ozone holes. The effects on ozone depletion arise because they support chemical reactions that produce active chlorine which catalyzes ozonedestruction, and also because they remove gaseous nitric acid, perturbing nitrogenand chlorine cycles in a way which increases ozone depletion.

As conversation flows from one subject to the next, Lucas casually mentions the Episode III’s principal villain could be a Separatist droid general. “I won’t limit it at this point to a droid. It could be an alien of some kind,” George clarifies. “I’m not sure if I want him to be human. It’s the Darth Maul. It’s the Jango Fett, Darth Vader.” “Male, though?” Rick asks. “I don’t care. It’s gotta be iconic. It’s gotta be pretty evil,” Lucas explains. The Making of Star Wars: Revenge of the Sith by J.W. Rinzler “Because my priority was environments, I didn’t focus on the droid general until the end of the week-at the last minute. The morning of the meeting, I sketched one, which I didn’t even like that much. But we put it out there, and George goes right up to it and says, ‘That’s the one.’ I mentioned that the genral might have organic eyes-George’s eyes lit up and he said, ‘Now that’s interesting.’” - Warren Fu

Henceforth you shall be known as Darth Vader.
