Known history:

Left Durotar when he came of age to travel to Tirisfal, no real reason that he's yet stated, at any rate. Was infected with plague when in the Ghostlands and died three days after, shortly rising as a feral zombie, then aligning with the Forsaken. His work on alchemy and the Forsaken in general was later noticed by the Royal Society, and he was appointed Apothecary. Recently he has been researching for the plague's cure, with the help of Troll Witch-doctors as well as Apothecaries.
