The Legend
W'soran
Originally the High Priest of Lahmia during the days when the Tomb Kings had skin, W'soran was chosen by Queen Neferata to drink a magic cocktail and become one of the first Vampires.
He seized the opportunity to do what he had always wanted to do and...promptly sealed himself up in the Great Library of Nehekhara to read. Forever.
He turned some minions who shared his interest in avoiding social contact, but otherwise just sat reading until Alcadizaar laid siege to the city, where he left the confines of the library and raised a fuckload of Undead for Abhorash to lead. He then went right back to reading, not realizing or caring what was happening until the moment the Great Library was on fire.
Many of his followers stayed in the building, but he and the ones without WIS as a dump stat loaded up on as many books as they could and hit the road. As the library burned behind them the dreams of Tomb Kings players taking Forbidden Lore, as well as humans being able to claim they figured out magic without Keeb help, went up in smoke.
The remaining Vampires united under Nagash and fought back against the humans, but meddling Skaven caused them to lose. While the Bloodline leaders fought amongst each other, W'soran hid in Nagash's library and contentedly read. When the others fled, W'soran stayed with Nagash and rode in his own chariot doing the Level 4 Wizard thing. As a reward, Nagash gave him an autographed copy of one of his nine books series "Necromancy and You" as well as a Black Pyramid tote bag. After Nagash was killed W'soran turned more nerds into Vampires and crossed the impassible mountains to join Ushoran, who had been kind of a bro to him. He aided Ushorsn in building up the power of Strigos, and helped Ushoran claim the Crown of Nagash. An afterthought came that Nagash wouldn't have been to pleased about that, so W'soran fled.
He made a pact with the leader of a human tribe named Vorag Bloodytooth, who in exchange for helping make him powerful built W'soran a fantastic laboratory fortress. Here W'soran conducted many EEEEEEEVIL experiments.
