The Ark's Core

The Ark's center is a vast room, made to house the energy of the 7 Chaos Emeralds, the artificial Emerald Shrine, and the monster known as the Bio Lizard. Water rushes from the center of the room and out in all directions. There is only one dry pathway that leads from outside to the Shrine. The Ark had been programed that should there be a failure in firing the Eclipse Cannon that the Ark would use the Emerald's energy to make itself go on a direct collision with earth to kill all life. Obviously DR Gerald was insane at the point he made this. Since then the program has been disabled and it is not known where the Bio Lizard is, if it even lives anymore.
