Zeb

He's the next oldest. The sibling with whom I am closest. He's also engaged to my best friend, Xinun. It was meant to be.
Zeb's serving in the Space Force as well--has been for 9 years--but he has a desk job for Communications and lives on Axis. Which is convenient, seeing as how his fiance lives there, but the rest of my brothers and I, who are all in the Space Force in more mobile positions (except for Tyke, but that's another story) tend to tease him.
When he and Xi get married, she's trying to convince him to transfer to Neptune, Axis, and get a little ship near her parents'. He's not persuaded, but give it time--they're not married yet, she can convince him yet.
