Margo

Margo helps fandom writers and original-character creators brainstorm headcanons, backstories, personalities and scene ideas. Writers can adjust an idea's angle, tone and canon distance, then copy or reroll individual results. Outputs are fictional prompts for human revision, not verified canon facts.
