Worldbuilding — StreamUniverse / BattleRoyale

Production-facing outline for set design, props, costume-adjacent dressing, and background art. Applies across the whole StreamUniverse continuity; BattleRoyale is the first film rendered under these rules.

Canon anchor: Rain's origin book series is Legend. Use it as the genre compass — post-medieval modernizing world, not high-fantasy escapism, not sci-fi. StreamUniverse is Legend-adjacent in tone and technology.

1. The era in one sentence

A post-medieval world in which magic, mathematics, and primitive computer systems have entered a creative union — and that union is rebuilding the culture's material world from the ground up.

Nobody is modern. Nobody is medieval. Everyone is in the middle of becoming something new.

2. The dominant aesthetic: Catmull-Baroque

The draconian cultural memory idolizes the Baroque — ornate, romantic, passionate furniture and architecture. That longing never went away. But the manufacturing stack has changed: every form must now be mathematically constructable from first principles, on primitive machines, with limited polygon budget.

The result is a hybrid:

"The 1600s copulated with 1980s–90s primitive computer graphics for the manufacturing of furniture and architecture."

Call it Catmull-Baroque — named after subdivision-surface math (Catmull-Clark, Catmull-Rom) that allows procedurally smooth curls from low-poly cages. It is baroque-lite because baroque feels like home. It is procedural because that's what the tech allows.

Visual rules

• Subdivision-ornament. Fleur-de-lis, scrollwork, cabochons, cartouches — all reduced to low-poly cages with smoothed topology that read as baroque at a glance, reveal polygon count up close.
• Discrete meshes. Every ornament is a distinct, named, reusable asset. The MOTD frame is a textbook example: ornate, gilded, clearly its own object, clearly not hand-carved-in-place.
• Limited palette per object. Gold/amber/wood-grain on one piece; next piece gets a different triplet. No continuous rich surfaces — each object is a mesh with per-face materials.
• Gilded lighting, low-poly silhouette. Amber and topaz cabochons glint like polished gemstones; the underlying form is angular enough that, rim-lit, you can see the polygon edges.
• Where the machine shows through, leave it. Visible wireframes carved into stone, exposed parametric curves on balustrades, procedural repeats that quantize instead of flow — these are features, not mistakes. The culture likes the tell.

Do / Don't

• Do: gold leaf on low-poly curl; ornament as discrete placeable asset; subdivision cages visible on close inspection.
• Don't: photoreal baroque detail (wrong era); smooth hand-carved continuity (not how they build); fully modern sleekness (wrong vibe).

3. The Court specifically — Catmull-Baroque vs Brutae

The Colosseum and the broader court have one additional layer: their material substrate is raw concrete. Slabs, poured forms, cold masses, unornamented volume.

On top of that substrate, Catmull-Baroque is passionately murdering Brutae.

• Brutae: the dying brutalism. Raw-concrete architecture that once sufficed — plain slabs, unadorned columns, functional planes. It is losing.
• Catmull-Baroque is being carved, bolted, gilded, and overlaid onto every brutalist surface it can reach. Procedural fleur-de-lis sunk into poured concrete. Low-poly scrollwork pinned to slab walls. Gilded cartouches nailed over blast-form seams. Chat-scroll runes chiseled into the concrete friezes of the upper tiers.
• The clash is intentional and violent. It should feel like one era is actively killing another in the same frame. A concrete column with a gold Catmull-Clark capital bolted onto it. A brutalist archway stuffed with subdivided cabochons. The court does not hide the seams.

Practical effect on court shots

• Material: raw concrete everywhere the ornament isn't.
• Ornament: everywhere the concrete lets it land.
• Lighting: warm rim (gold/amber) on ornament; cool fill (grey/blue) on raw concrete. The lighting itself enforces the clash.
• Mood: a harsh, beautiful cathedral of a construction site that has been won by the decorators and not yet cleaned up after.

4. The character-style cocktail — the Gumball Rule

Characters come from different native universes and render in different native styles. Do not homogenize them. Do not pick one rendering pipeline. The tonal reference is The Amazing World of Gumball: 2D characters, 3D characters, photo-real backgrounds, and puppet characters all coexist in the same frame, without comment, and the show is funnier and more itself for it.

Per-character rendering cast (BR roster)

• Raincloud — adult anthro dragon, painterly / clean-cartoon hybrid (matches his refs: flat-color PFP crop + painted vtuber still both canonical).
• Azure — JoJo-stylized anime figure, bold-ink Killer Queen silhouette, with the literal-object John Cena tee as a physical-prop gag.
• Ubear — cartoon-mascot bear with a steampunk-rendered mechanical arm (two render languages on one body; leave the seam visible).
• Starboy — chibi proportions, brighter saturation, anime-idol shading.
• NotoriousRooster — silhouette-first Disney-Robin-Hood-era hand-drawn cel feel, beak-in-a-hood, everything else absent.
• Agate — painted chimera, softer edges, semi-realistic feathering.
• Adrian — grounded 2D character-art, closest to a "normal" cartoon human; the anchor against which the stylistic clash reads.

Gumball Rule do / don't

• Do: keep each character in their own render language, on their own shading logic, even when they share a frame. Let their edge-treatments disagree.
• Do: stage them together as if nobody has noticed. No character ever reacts to another character being "differently drawn." That is the joke, and it is never spoken.
• Don't: pick a unifying filter or grade in post that smooths the cast into one look. The clash is the point.
• Don't: write dialogue that lampshades the stylistic difference. Not once.

5. How the three layers interact in a shot

Any given shot in BR is a three-way collision:

1. Brutae (raw concrete substrate — passive, losing).
2. Catmull-Baroque (low-poly gilded ornament — active, winning, murdering Brutae).
3. The character cocktail (each figure in their native rendering language — indifferent to both of the above).

Composition tip: do not try to reconcile the three. The frame should feel slightly insane, and it should feel like home anyway. That is the StreamUniverse.

6. Quick glossary for the team

• Catmull-Baroque — dominant aesthetic. Procedurally-built neo-baroque ornament, subdivision-surface ornament, low-poly curls, per-object materials, amber/gold lighting.
• Brutae — the dying brutalism. Raw concrete. Losing ground.
• The Gumball Rule — characters render in their native styles and never comment on the difference.
• Legend-compass — when in doubt about tone, ask "would this fit in the Legend book series?" If no, rework.

7. Writing-style rules (project-wide)

Pronoun policy

• Never use singular they/them/their/themself in narration, action lines, or character notes. Plural they (referring to multiple entities) is fine.
• Default to he when a character's gender is unspecified, unknown, or strategically obscured.
• Androgyno-mystery characters (e.g. Rooster) — default to he in all public-facing prose. The room assumes male because the affect is loud/boisterous and because the chosen persona (rooster) implies male; neither is real evidence, but both function as social camouflage and the prose should honor the illusion. Reserve she only for writer-frame reality notes (character-sheet Identity sections, later-installment reveal beats). The voice itself is androgynous—nothing in speech or behavior concretely establishes sex—so the he default is the room's assumption speaking, not canon fact.
• Noname is presumed male for prose pronouns (default-he policy) regardless of in-canon gender being unknown.
• Agate uses she/her exclusively in all public-facing prose, narration, and writer-meta. Trans MTF in canon; the writer's private pattern-lock reads her as male, but the public film respects her preference. Never he/him/his for Agate in any committed file.
• This rule applies to all .md character notes, the .fountain script, and any future writing in Story/. Verbatim quotes in Evidence sections may keep their original pronouns.
