Seven Morrow Days

The main villains of the Keys to the Kingdom series. The seven Trustees of the Architect, named after the seven days of the week, are superior Denizens who disobeyed the Will and chose to keep the Keys and their demesnes instead of giving them to the Rightful Heir, and causing their own demise. They broke the Will into seven pieces, then separated and concealed each of the pieces. However they could not entirely resist the Will's destructive influence, so in time each of the Trustee's nature changed and each became afflicted with one of the Seven Deadly Sins. Drowned Wednesday is the only Trustee who, after breaking it, changed her mind and wished to follow the Will, but was stopped by all Trustees, with the exception of Monday. Minus the power given to them by the Architect's Keys, they are ordinary, but extremely strong and resilient Denizens, though they can be killed (the exception being Saturday, who as well as being a key holder, is also a skilled sorcerer).
