As this is an 'Open Doors' Chantry the policies about membership are quite simple but functional. As you would with anyone's house the rules are mostly forms of politeness extended to both the host and any guests present.
Don't bring harm to any within the Chantry.
Don't bring any outside harm to the Chantry.
Leave your Drama at the door.
The "Leadership" of the Chantry was given to the woman who called the magi of Prospect together to discuss its formation, Eloise. Given the name "House Mom" by a rather impetuous Hollow One, she has no more authority than one would have over their own house. While guests are in the Chantry they are asked to be mindful of their Manners and respectful of her position.
Essentially a coordinator of the activities of the Chantry, the House Mom is usually the 'go-to' person should anything happen or need to happen within the Chantry.
Sunday Supper: Although originally announced as a joke, the members of the Chantry, in the spirit of cooperation and fostering good will to those who are associated with it, try and meet once a week for a pot-luck dinner.
