Corrupted diarch of Caemeris, Baachelaus, with his gaoler Voloc,
breach the world of Arglethium. They are pursued by Assumpta,
co-ruler of Caemeris, who has been doomed to an eternal quest to
set Baachelaus free.
A prism forged in the last days of Caemeris from the tears of
Assumpta is hidden on Arglethium by the custodian Norbu.
Lusting to seize control of the power within the prism, Voloc
possesses the despot Ranik and sets the Kingdoms of the Middling
lands to war to seek out the sacred tears.
Assumpta calls the ancestors of the fi rst tribes of Arglethium, Ange
Tsaed desert dweller, Gildas Gol exiled warrior, Kado heir to the
Drax Empire and Sa-Tuc assassin, to fulfi l a covenant made in the
beginning days with Norbu to protect the prism.
Suspicious of the gods, but with no choice as their world spirals
toward annihilation, Ange, Gildas, Sa-Tuc and Kado are drawn
into the mysteries of the prism, and an ancient war raging since the
dawn of the fi rst stars.
