Big Castle has a very deceptive name, considering that it is merely a small wooden house on a floating bit of rock the aforementioned island, near the middle of the Mansus. It came into being shortly after the Emperor's awakening, appearing out of thin air when no one was looking. The Emperor comically refers to it as his keep, though his intentions of making it one are far less pretentious. The interior is cozy and covers the bare essentials of comfort and aesthetic. A nice fireplace, a little wooden table, a makeshift kitchen and a straw bed for resting. The only thing off is the throne, of course.
