Courtesy of Lilith, MyCastle is your personal, parallel universe base of operations to rest, recoup, and resupply in between battles! Your MyCastle will be unlocked after selecting your path in Chapter 6. Through MyCastle, you can interact with your characters, purchase new weapons and items to use in battle or promote units, gather resources to use in certain facilities, and more!
You can customize the layout and theme of your castle to your tastes. Birthright and Conquest each have 3 castle layouts and regional buildings, while Revelations has access to all of them. Once you have your castle set up, you can show it off to the world online, and visit other people’s MyCastles.
