Persona Poem Character Build

Help me develop a persona voice for a dramatic monologue poem.

Character: {{character}}
Historical period or setting: {{setting}}
Key emotional truth to reveal: {{truth}}

Build the persona by defining:
1. Their speech patterns, vocabulary, verbal tics
2. What they would notice vs. overlook
3. Their self-deceptions and blind spots
4. What they want the listener to believe
5. What slips through despite their control

Then draft opening lines in their authentic voice.

The voice must feel lived-in, not performed.
