Jupiter Sky

Of all the human offshoots in the solar system, the Jovians were the strangest. They eschewed material possessions (save for a few libraries, floating eternally above the clouds of Jupiter) and folded their bodies into sleek black darts, with scapulae for wings. Their technology allowed them to generate thrust and motion with a thought and has since proven impossible to replicate, and not for lack of trying. It is simply too difficult for non-Jovians to understand. They described it as “understanding the leakage between multiple layers of simulations” and investigations into their writing hint at some sort of powerful understanding of information theory.
Of note; the sophisticated noses of Jovians are commonly confused for their recessed mouths.
