Originally, Valenko was a mage of forerunners the Progenitors who had made an agreement with one of the ancient fiends. In exchange for a cure against the sunlight, the elder fiend would tell him about Kindred society.
Valenko succeeded in that the vampire could stay in direct sunlight for several hours without significant burns, but he needed Valenko for supplies. As a result, he embraced him to have his supplies granted for all eternity. Valenko avenged himself by giving him the wrong ointment and watching as the Tzimisce burned away in the sun. Afterwards, he destroyed his formular, believing it to be too powerful.
For a long time, he served the Sabbat, in secret hoping to abandon them at one point and return to the Technocracy. His current fate is unknown, but it seems possible that he was part of the conspiracy of the True Black Hand and destroyed.
