Series drift is usually blamed on the model, the way a lost trail is blamed on the map. Check the log instead. The character was described from memory at every job, and memory edits as it goes: “shoulder-length violet hair” at the trailhead becomes “flowing purple locks” three waypoints later, and the audience watches a stranger quietly take over the expedition. The repair is clerical, not technical. Write the character down once, in an entry you paste rather than retype — the first page of the log that every later frame is checked against.
Five fixed lines, always in order
A working first entry holds five things. Age — a number, always 25 or over. Hair — colour, length and one habitual style. Build — two or three words, no more. Face — one or two details that endure every crop. Signature — the mole, the ring, the mark that survives even a tight frame. Everything else belongs to the route line: outfit, room, hour, light, pose. Route lines are meant to change at every job. Entry lines are not.
Two habits keep the first entry honest over a long route. Lines are stated plainly and positively — “shoulder-length deep violet hair in slicked-back waves with a sharp side part” survives generation, while “beautiful hair” is reinterpreted at every attempt. And the entry is versioned. When the character is deliberately changed — a new cut, a new signature — the new text is saved as version two with a date, so an old set can still be remade exactly as it was first logged.
Working from the entry
Production then becomes a calm routine. Pair the entry with route lines that share one setting and one light, and generate the set at the standard model’s 6-credit cost. Keep the best third. Spend on repairs, transfers and upscales only after the cull. When a frame returns off character, the cause is almost always visible in the log: a route line contradicted an entry line, or a line was too vague to hold. Both are fixed on paper, at the desk — not by hunting through settings at the tool.
What a first entry cannot do
It cannot hold a character who was never decided. If the lines are adjectives — lovely, striking, perfect — no system on any trail will keep her, because there is nothing fixed to check against. Decide her on paper first. The first log entry is not where the imagination happens; it is where the imagination is kept, frame after frame, so that months from now a new leg of the series can still be read against the very first entry and found to be the same woman.
