If our homes have doors leading into the spiral, then why can't wizards also see their homes as desitnations in spiral doors? We can only equip one home at a time, but people with multiple homes have to keep switching or set up a network of teleporters.
Why can't KI code the spiral door so that it has one a button that selects either a list of spiral worlds and a list of our homes? It would just be adding a tab and pulling a list that ties to what equipped castles and the home button already does. Our wizards techinically have "spiral keys" to their own houses right? This would let us travel more freely between homes and maybe even list friends houses too.
