Varlos
Varlos was a former Brother of the Darksmith Collective. He was assigned the prestigous task for an undisclosed client of creating life. His masterpiece was to create the Eternity Crystal.
Aware of its power he fled the Darksmiths, taking the crystal and Gisella (the 'daughter' he had created) with him. He hid Gisella on Flydon Maxima for her own safety and took the Crystal which he buried on the Moon until he had found a way of destroying it. (TDL: The Depths of Despair, The Dust of Ages)
He settled in Paris in 1895, around the same time as a time-Vampire stalked the streets. He first feared he had been found. When it transpired that the vampire had followed him through the Vortex he sought to keep it hushed up so as not to draw the Darksmiths' attention.
He assumed the identity of the Vampire's first kill, the much respected Baron De Guerre. Using this guise he worked alongside Inspector DuPont, who lead the investigation.
In order to defeat the Vampire he gave his own life when he drained the vampires time-energy using his own body, a mock Eternity Crystal and Gisella. (TDL: Vampire of Paris)
