Vostok

Vostok grew up in the Zephyr Steppes, where he was the only nocturnal dragon for miles around him. He loved the stars and astronomy, but learning about them was difficult, because he couldn't attend school while being nocturnal, so he read everything he could about space and made his own star charts during his free time (what a NERD). Eventually he worked up enough money to go to school in the Starfall Aisles to study astronomy.

He was in school for a long time, because he'd never had any formal education, and his math skills were really lacking. But he labored for YEARS (almost 15, probably) and got through with a PhD in astronomy. In grad school, he met the love of his life, Chandra, a chemist from Arcane who had grown up with astronomy forced on him and hated it with a passion. The two were in many ways polar opposites, but they both loved math (NEEEEEERDS) and learning new things, and wanted to make big differences (hopefully positive) in their fields of study.

After they graduated, Chandra got a job working at a space agency in the northern Aisles, and since Vostok was an astronomer with a huge mathematical background, he got a job there as an astrodynamicist. But a few months after they got settled, Arcane faced a huge recession, and a lot of businesses had to lay off workers. The space agency moved base completely over to Lightning, where there was grant money for the sciences and especially engineering fields. But Vostok was devastated, because living in the Aisles and studying astronomy had lowkey been his dream since he was a kid.

But tl;dr the economy in Arcane came back and they realized it was cheaper to launch crap from there anyways, so they built another launchpad there, and Vostok works there for about half the year. He probably also works at an observatory in his free time because LOL poor guy.
