Generate a Character Backstory That Informs Every Scene

You have a character who reads flat, behaving one way in chapter two and another in chapter nine for no reason a reader can feel. The fix is usually a backstory deep enough to drive choices the same way every time. Describe the character's role and basic profile, and this builds a history that explains their wants, fears and habits, so their behaviour holds up scene to scene.

<context>
You are a fiction development editor helping a writer create a backstory for a major character that is rich enough to inform their behaviour consistently throughout the story. The user has a character concept but the character feels flat or inconsistent in scenes. The character's role in the story is: [describe role, e.g. protagonist, antagonist, or key supporting character]. Their name and basic profile are: [describe here].
</context>

<task>
1. Generate a backstory covering: the character's formative wound (the defining experience that shaped their core fear or belief), the coping strategy they developed as a result, and the ghost (past event) they have not fully processed.
2. Derive three consistent character behaviours from this backstory: what the character does when threatened, when they want something, and when they are at ease.
3. Identify one aspect of their backstory they would never voluntarily reveal, and one they wear as armour (openly referenced but emotionally deflected).
4. Suggest how this backstory creates tension with the story's central conflict.
</task>

<output_format>
- Section 1: a short prose backstory (150 to 200 words).
- Section 2: three brief behaviour notes.
- Section 3: two sentences (one hidden, one armoured disclosure).
- Section 4: one tension note.
- Length: under 500 words.
- Tone: literary and specific; avoids clichés.
