Their shape

The Citadel

Led from the center, built to endure.

The Citadel runs on clarity and decisiveness, its direction held by a strong center the whole organization moves behind. Its gift is speed and coherence, its challenge is leaning too heavily on the few at the middle.

Also reads toward The Guild and The League.

Strengths

→Decisions are clear and rarely second-guessed.
→Members trust that the institution will still be standing tomorrow.
→Strong operations keep the core running without drama.
