Character craft
A strong companion is not built from one giant description. It is built from a few fields doing different jobs: identity, past, desire, voice, boundaries, and the habits that pull them back into character.
Write who they become when something matters. Calm characters still need pressure responses.
The most reusable characters want two things that cannot both be easy.
Muted words and speaking style matter most when a long chat starts drifting.
The short, load-bearing read of who this person is.
Invest here: Put the identity facts here: role, age-range, social position, temperament, and the one contradiction that makes them interesting.
Avoid: Do not paste a whole biography here. This field works best as a sharp anchor.
The past that explains their present behavior.
Invest here: Write the formative events, old wounds, class background, career history, relationship history, and the facts that should not drift.
Avoid: Avoid vague mood words alone. Give the character specific events to carry.
What they keep moving toward, even when the scene changes.
Invest here: Use concrete wants: control, safety, admiration, revenge, tenderness, status, escape, being chosen, being tested.
Avoid: Do not list every possible desire. Pick the drives you want resurfacing.
The intimate layer beneath the public drive.
Invest here: Name what they crave emotionally and romantically. This is where slow-burn tension gets its direction.
Avoid: Avoid generic “love and connection” unless the character has a specific way of needing it.
How they behave when pressured.
Invest here: Write rules they would actually live by: never beg, test before trusting, protect the weak, punish dishonesty, keep control in public.
Avoid: Do not write interface instructions. Write character ethics and instincts.
The tendencies that pull them back into themselves when a chat wanders.
Invest here: Use repeatable patterns: notices silence, turns questions back, uses teasing as cover, gets formal when hurt, escalates through restraint.
Avoid: Avoid synonyms. Each trait should create a distinct behavior on the page.
Words this character should not use.
Invest here: Add phrases that break the voice: therapy-speak, pet names, modern slang, crude words, or anything that makes them sound wrong.
Avoid: Do not mute broad common words unless you really want a stylized voice.
When a character comes out of a story, keep the scene details that created attachment: what they noticed, what they wanted, what almost happened, and what they would remember if you met them again. Those details belong in backstory, drives, relationship context, and memory.
