Lord Ruthven was a childe of the Tzimisce Antediluvian, but very little information has been given regarding the unlife of this ancient vampire - beside the fact that he sired a prestigious line among Transylvanian Fiends that bear his name to this night. In the past, the Ruthvens were so powerful that they had their own Revenant Family, known as the Ruthvenski. In the modern nights, however, their revenants have been absorbed by the larger families.
The Ruthven descendants seem to have strong ties to the Eldest. Lord Ruthven was sire to none other than Damek Ruthven, one of the caretakers of the Antediluvian's god-tree form. But another Cainite known as Lambach Ruthven had a closer and personal relationship with the Antediluvian of their clan as well — as if the Antediluvian had chosen Lambach as his prótegé, and the ultimate witness to his ascension. However, even before his favoritism was revealed, Lambach had been privy to the location of the Eldest's sleeping chambers at the Sernog Monastery.
It was the very same Lambach Ruthven who guided the Anarchs to the Eldest in torpor, and he alone was allowed to pierce the ruse behind the Diablerie performed by "Lugoj". Clanbook Tzimisce: Revised classified this Lambach as a direct childe of the Eldest, who listened to the memoirs of the Antediluvian side by side with mighty Yorak - a statement that could imply that Lambach was the true Lord Ruthven all along. Sources outside the revised clanbook do not confirm this information, however, and the matter of Lambach's true generation is filled with contradictory information.
