Wisterian Arbor
The Wisterian Arbor is a knightly order dedicated to the Uncta Eleah of the Arch. The order maintains a small estate in Crownhold with extensive gardens, a meeting-hall, and a small library specializing in architecture, building plans, and civil engineering. Newly-knighted followers of Eleah are invited to a Great Feast, held after the Summer Vigil and attended by most of the Order. If found promising, they are assigned a mentor for a year, and are often asked to assist in a grand project. The next year at the Grand Feast they are accepted if they have been deemed worthy.
The Order is dedicated to promoting civic beauty, and often shares knowledge of what works and doesn't in their respective domains. It also serves as a clearinghouse for skilled artisans, artists, and craftsmen that specialize in large-scale projects.
The Grand Arborist is traditionally named Royal Curator for the Arcadae of the Royal Palace. This role is mostly ceremonial, and a dedicated staff of curators actually do the day-to-day work maintaining the collections.
