Their shape
The Guild
Where mastery is the price of belonging.
The Guild is the keeper of a craft and its standards, where belonging means meeting a real bar. Its gift is depth and trusted expertise, its challenge is opening up to newcomers and new ways.
Also reads toward The Citadel and The Legacy.
