Khys Enmies, a priest of the heretic Laonan sect in pre-apocalyptic Silistra was fathered by a man from the planet of Mi'ysten where its inhabitants are taught to use their superior psychic powers from an early age.

During the apocalyptic era named the 'hide days', the people of Silistra were divided into hides, settlements and related lineages formed on their underground shelters following the apocalypse and there was no common system or leadership binding them.

Later, he settled at the remote Lake of Horns and through a series of eugenics experiments, created through favourable women of Silistra a new race named the Lake-Born that inherited distinguished traits of Khys himself.

Immediately after the Well Astria battle, Estri, Chayin and Sereth are captured by Khys, tyrant ruler of Silistra (“the dharen”) and held hostage for over 2 years.

Estri's journey of self-awareness and the trio's fulfillment of the “Seker’oth prophecy” (which means “Golden Sword”) conclude in The Carnelian Throne, the final book in the Silistra series.
