Every invented world needs one object drawn carefully enough that you believe the rest of it. The Excelsior is mine. A swept silver hull with blue wingtips, engines lit orange, crossing the curve of the Earth with a small hard sun behind it and two planets holding their distance. I built it as a digital illustration so that it could be reused across the whole project rather than redrawn each time, and it later ran in the artbook beside its own specification panel.
