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 Republic and The Guild.
