The Celestial Atlas is the Universe's interactive 3D planetarium: a way to navigate the cosmic expanse of Xdripia by moving through it rather than reading about it. Primordial spheres, sectors, star systems and planets are all present, and all navigation between them happens inside a single WebGL canvas built with React Three Fiber. There are no separate pages to browse — the Atlas is one experience, and everything it offers is reached by moving within it.
What it is good at
Arrangement. The Atlas answers where something is, what is near it, and how the levels of Xdripian space nest inside one another. Those are questions that text answers badly and a spatial interface answers immediately, which is precisely why it exists alongside a Codex that already documents every one of these places in words.
What it is not
It is not a lore database. Records, attributes, relationships, histories and linked entities live in the Codex, which publishes several hundred celestial records as readable pages. It is not a game, and it holds no player state. And it is not a substitute for reading — an evening in the Atlas will teach you the shape of the Universe and almost none of its meaning.
Before you open it
A single-page WebGL experience needs a capable browser with hardware acceleration. If it will not start, the Codex holds the same locations as text, which is a complete alternative for reading if not for exploring.
Because the Atlas is one canvas, individual locations inside it are not separately addressable pages. Cite the Codex record when you need a stable link to a place.
