The reference masters
Each image is shown on the page it is about, and is authoritative only for the properties its row lists: a reference is used by property, never as total canon. Which master governs what is VISUAL §23. Exploration images are not shown.

Masters for Actives no class carries now.

humans/character_master_impale_001.png 1536 × 1024
Fills CHARACTER_MASTER_IMPALE
Canonical for Her exact design: build, hair, robe, coat, trousers, gear, sword, colours; the figure every Impale sheet is drawn from (VISUAL §22). Brief: ../records/Yui/BRIEF.md.
Not canonical for Its side view, which is three-quarter: sheets are drawn in true side view. Its sword: the owner replaced it with a jian (../records/Yui/BRIEF.md §3). Its lighting: sprites keep near-neutral shading for Unity (D-340).
What it shows
Yui, the figure of the Active Impale: front, side (three-quarter) and back views, a bust, the sword alone; hand-drawn illustration. Chosen by the owner 2026-09-28 as master 003 of the rework (../records/Yui/).

humans/character_master_barrier_001.png 1536 × 1024
Fills CHARACTER_MASTER_BARRIER
Canonical for His exact design: build, helmet, coral collar and height stone, harness, kilt, greaves, sandals, spear, shield; the cast pose. Brief: ../records/Barrier/BRIEF.md.
Not canonical for The shield's stone, drawn as a tidy lozenge of stacked blocks where it must be one jagged found fragment (UNIVERSE §14); the stone does not flare gold-white in the cast pose (D-390); brass heavier on the body than the brief asks; its lighting (sprites keep near-neutral shading, D-340).
What it shows
Barrier's figure, a Red Earth Palace Guard (D-389, D-390): front, side and back views, a bust, the cast pose (low, the body tucked behind the shield thrust forward, the spear upright in hand), the shield and spear alone; hand-drawn illustration. Chosen by the owner 2026-10-01 as master 001 (../records/Barrier/).
Missing masters
| Master | Defines | Status |
|---|---|---|
| GAMEPLAY_ENTITY_STYLE_MASTER | Pixel density, outlines, sprite shading, gameplay abstraction, sprite-level proportions. | Missing. No image defines sprite rendering: the gameplay master has no consistent pixel grid, the human master's sprites are chibi, the Yui sheet is an exploration. Its numbers are part of the open art spec (D-083, ../proposals/art-spec-v0.3.md). |
| HD2D_CHARACTER_MASTER | Named in the owner's AI guide for sprite generation; not in VISUAL §23. | Missing. Probably the same role as GAMEPLAY_ENTITY_STYLE_MASTER under an earlier name — OPEN (OQ-A8). Treat them as one until the owner says otherwise. |
| CREATURE_VISUAL_MASTER | Biological language and creature diversity. | Missing. The three creature sheets are exploration only. |
| CHARACTER_MASTER_<ID> | The exact design of one Active's figure (D-080). | Impale, Barrier, the Cartographer, the Shieldbearer, the Pilot, the Berserker, the Bloodletter, the Sapper, the Archeologist, the Chaplain, the Frost Mage, the Apothecary, the Gunner, the Archer, the Assassin and the Porter (one placeholder for every Passive) filled (humans/character_master_impale_001.png, humans/character_master_barrier_001.png, humans/character_master_cartographer_001.png, humans/character_master_shieldbearer_001.png, humans/character_master_pilot_001.png, humans/character_master_berserker_001.png, humans/character_master_bloodletter_001.png, humans/character_master_sapper_001.png, humans/character_master_archeologist_001.png, humans/character_master_chaplain_001.png, humans/character_master_frostmage_001.png, humans/character_master_apothecary_001.png, humans/character_master_gunner_001.png, humans/character_master_archer_001.png, humans/character_master_assassin_001.png, humans/character_master_porter_001.png); the other Actives have none yet. |
| ANIMATION_MASTER_<ID> | That figure's exact gameplay animation identity. | None yet — one per Active. |
| Creature-derived equipment reference | Processed alien biology (UNIVERSE §22). | Not in this folder. UNIVERSE §22 cites it (a black-carapace family, one species, not universal); no image here matches. |
