Huge solid stone gates guard the entrance into the Sumidoru. The gates are formed of the natural rock face of the mountain, they were expertly tended so that the gates would never be revealed. The huge gates were composed of many other gates, of many different sizes, each door only opening when necessary. The doors are supported by an engineering marvel of security systems and balanced pulleys. The system is designed to make the doors open with the push of a child or to set them off balance and seal them shut, there would be no opening them when they are shut, one would have to destroy them to get them open, or use exasperating magics to move the great gates. There are many traps and fail-safes designed into the security of the gates, even the tunnels behind the gates are rigged with defenses trained to activate in a breach of security. Hidden in the shadows are Kyoushu guards, ready to eliminate any threat to the Tribe.
