Phaeliea Sunsong was a magistrix, born a noble in the court of the Sun King with her twin sister Luminea and together they fought in the third war when Arthas laid siege to Quel’thalas. Phaeliea a Mage from a prominent family, had always had a fascination with experimental magic. Her sister was a Priestess, and they often were at odds with each other. Her mother was a Mage trainer and her father was also a Priest, however they were both killed by the undead scourge.
She was greatly affected by this tragedy, and never fully recovered from her grief and guilt for not doing enough to save her parents, as much as Luminea tried to give her comfort in their time of greatest tribulation.
When Prince Kael’thas left on his on his campaign, she readily joined his crusade, much to the chagrin of her sister, who decided to stay behind to help her people heal. Once she arrived on Draenor, she focused on her love of experimental magic and honed in into the darker arts and became a Warlock. She commanded a large portion of Kael’thas’ Warlocks, and at first she felt her choices were justified. After her Prince started to go down a path she couldn’t follow, she joined the Scryers in Shattrath to atone for her part in his campaign.
Once the Horde arrived, she was initially surprised that her people joined the faction that once also tried to destroy her home, but eventually she decided she would come back to Silvermoon and support her people. She reunited with her sister, and learned that she had become a Paladin, and Luminea was disgusted to see her sister fall so low as to make pacts with demons.
This tension came to a head once they both signed up for the Northrend campaign. Luminea went with Saurfang, hoping her sister would come with her, but Phaeliea decided she would rather assist the Forsaken and left via the Howling Fjord. They would not see each other until the final assault against the Lich King, and while the armies of the living were victorious, their relationship was irreparably broken.
She then became a wandering Warlock, always somehow involved in the Horde’s campaigns and conflicts, becoming a loyalist to Sylvanas and reveling in the burning of Darnassus. The irony of an Elven city being destroyed would have once disturbed her, but she had seen horrors beyond comprehension, and all the while her magical experiments became darker and more unhinged.
Now, she hides her dark appetites in the guise of being a champion of the Horde. After all, how better to acquire new tomes, artifacts, and ingredients for her machinations than by conquering those who would oppose her?
