I was suggesting That inside Bartleby since he is so vast , you can install new Portals to go to Wizard City new parts of WC . And have the main gate in the center. Nidavellir has those two doors on both sides of the entrance and was wondering if you were planning to use the3m for higher level wizards to fight in, this could bring the closure to the Coven story line and have new spells from there as well.
