Ghost of Tsushima - Castle Kaneda

For Castle Kaneda, we wanted the feeling of a Japanese castle fortress that had been taken over by the Mongolian invasion and were using it as a temporary base to further their campaign across Tsushima. What was their day to day like? How could we infuse it with their life and show their takeover, not only physical destruction, but culturally as well. I figured they'd hang up their flags, reforge their own weapons and gather around the fire to drink and tell war stories.
