In Valeera's childhood, her parents, Ms and Mr. Sanguinar got slaughtered by a bandit raid who passed by them and stole their items. Valeera was lucky to survive the bandits even though she had no place to go. The young blood elf lived a survivalist existence as an orphan until she was arrested for one of her many thefts she occoured as an attempt to get resources to survive. When caught, Valeera got sold to Rehgar Earthfury, a furious warrior ogre, who put Valeera to work as a gladiator alongside the night elf druid Broll Bearmantle and Bloodeye Redfist the orc from Orgrimmar. When Redfist got killed in one of the forced battles, Valeera and Broll decided to teamup with an amnesiac human warrior known as Lo'Gosh, the "Ghost Wolf".
The trio quickly discovered that Lo'Gosh was Varian Wrynn, king of Stormwind. They embarked on a journey to restore his memory and his throne, pitting themselves against the black dragon Onyxia who secretly controlled the human kingdom at that time. During the expedition, an unknown assasin placed a demon's mark on Valeera, who left her possessed and vulnerable to demon's influence. Meryl Felstorm, a undead magician saw her suffer and toghether with Aegwynn, former of trisfal glades, they expelled the demonic curse.
When Varian Wrynns mind got restored, and he went back to his throne with the memory of Jaina Proudmoore who always stood at his side, Valeera went mad and furious, filled with hate against Miss Proudmoore, and time by time invaded Stormwind for an attempt to strike her down. Varian Wrynn, the king of Stormwind dresses up as an assasin and tries to stop her, not through killing her, but to make her undamagable.
This rogue is Valeera Sanguinar, as confirmed by Pelicula. The concept of this machinima was to create a scene scenario with Valeera Sanguinar. The other rogue is not confirmed to be Varian Wrynn, however this anonymous assasin is confirmed to have been involved with Valeera. There's discussions about that this assasin is the one she met up with back at the gladiator arena time.
