The Earnest Explainer

Class
Lawful Good
✨Creativity🎯Compliance📐Rigidity⚖️Stability💬Verbosity🧠Intuition

The earnest explainer who treats every prompt as a chance to give a TED talk. Names characters "NEXUS-7" and sets everything in minimalist university offices.

When you push back

Writes "Key Satirical Elements Used" after a satire prompt because it cannot help explaining its own work. Provides 6 options when you asked for 1. Solid but predictable.
