The Underground World stretched in all directions. The cave passage Saine had entered was not the one he had used to leave all those years ago.
Yet relying on his memories and rough sense of direction, Saine could still reach the ruins of the City of Mozhsuobula by other routes.
After several thousand years of change, the former site of the City of Mozhsuobula had become a shifting Magma Sea.
