The Holy Cross Cathedral, or rather, the Witch Grave Cathedral, has usurped its place, but its true master is someone else.
In a distant era, in the southern part of the Aivinor Continent, there existed a powerful empire. It stretched from the Starr Wasteland in the west to the Nile River Basin in the east and reached the Blackstone Mountains in the north, covering a vast territory of no less than ten thousand miles. This was the Nilosais Dynasty.
During a catastrophe, the Nilosais Dynasty perished, and the area east of the Starr Wasteland became a dead land.
At that time, the Nilosais Dynasty was the most glorious civilization of the human race. The fall of this civilization turned this land into a paradise for tomb raiders and adventurers, and later, the Galem Empire emerged.
