In those last days of Lemuria sorcerers were given great power by the Old Ones who dwell in the primal dark, and the sorcerers ruled over men and compelled men to worship them as though they themselves were gods. The land became cursed and all manner of evil was indulged.
The statue of great Nodens was defiled in the temple and men swore that the elder gods of earth had lost their power. But in far Kadath Nodens watched and waited.
In time the stars wheeled in their eternal course and the Old Ones slept, in their dreams seeking out other worlds to corrupt. Great Nodens came down from Kadath to the land of Lemuria and the people cried out praises to him. But Nodens did not listen, he went to the high peak of Koltheg-Kla and there he did awaken the fire worm that is the child of Cthugha, and the fire worm devoured the foundations of the land of Lemuria that it would sink beneath the boiling seas.
All the tribes of Lemuria were destroyed but a few of the Sorcerers were gifted with the sight of things future and past, knowing what was to come they prepared spells and philtres to preserve their bodies and containers for the preservation of their dark souls. For in time the stars would wheel again, even great Nodens would fade from memory and the Old Ones stir from their dreaming, then would the sorcerers rise and the tribes of man bow down to them again.
