As a newly arisen Forsaken you encounter a young woman by the name of Lilian Voss. Like you she has recently been resurrected into the life of the walking undead, however she is not adjusting well. The Forsaken have a fairly simple philosophy about the recently awakened, you either serve Sylvanas or you die permanently. They give you the illusion of choice but that is the sum of your options. They will grant you some time to come to grips with this if they feel there is potential for you to come around to their way of thinking. It is this "give her time" path that is left open for Lilian and leads to all sorts of interesting encounters.
Lilian Voss is no ordinary corpse. To be perfectly honest she doesn't really have a classification other than "undead" but there are a few things that lead me to place her in the "rogue" family, not the least of which being that when she first runs off you find her hiding out behind the rogue trainer or displaying our trade mark skill "stealth". A Scarlet Crusader in life, her father is an area ranking priest who groomed her to be a weapon against the undead. Unfortunately with her recent transformation her usefulness to him has reached its end. Lilian finds herself torn between the life she once lead and one she now finds herself presented with.
The Scarlet Crusade is very aware of what Lilian is capable of. When Lilian attempts to contact her father, thinking he will protect her, she instead discovers that despite who she was in life, the Scarlet Crusade holds true to its ideals. Her Father orders her execution at the hands of her one time friend. Declared a "witch" along with all the usual foul names they bestow upon the Forsaken, she escapes, bewildered and enraged.
It is when faced with second death that Lilian's true nature emerges. Lilian's education while living was very well rounded. Not only was she trained in the traditional assassin arts of stealth, weaponry, and martial arts but also sorcery. When you first stumble across some of Lilian's handy work it is the evidence of this added element that grabs your attention. All of Lilian's kills glow with purple fire. The Forsaken generally prefer that corpses remain in one piece, (spare body parts or future Forsaken you understand) so this could be a problem. However Lilian demonstrates that while this is her preferred method of disposing of people, she can show profound creativity, as displayed with Captain Sanders, who she suspends by one foot at the outskirts of his camp.
When you encounter Lilian for the final time at Captain Sander's corpse she lets you know that she could easily dispose of you just as she has all the others but instead she is going to allow you to help her obtain her revenge. Her father High Priest Voss, is hiding surrounded by flunkies in his tower to the west of Scarlet Monastery. For creating a killer, rejecting her in her hour of need, then ordering her death, Voss must now reap the rewards. You need only to escort Lilian there. As a rogue this is of course incredibly easy, you can both stealth by every thing, however as any other class you will also find it rather simple as Lilian will quickly dispatch the Scarlet Guards in the area. (It reminded me a bit of the scene in Blind where the Rogue was entering Stormwind Keep, not quite that quick but impressive for a level 10.) Once you get to the tower don't let Lilian out of your sight because she quickly gets to the matter at hand, confronting her Father, if you blink, you will miss it.
After delivering her final embrace Lilian disappears, but her mark remains on those who have encountered her. As High Executor Derrington remarks "With power like hers, we could do incredible things." Lets explore that for a moment. The Deathstalkers are in shambles after Varimathras' betrayal of Sylvanas, many question their loyalty, constantly looking over their shoulders. Now lets say they manged to bring into their ranks a recruit like Lilian and adopted her methods? Sylvanas right now is fighting a war on two fronts not just literally with the Alliance but also within the Horde and their perceptions of the Forsaken. At the moment she is winning the physical war as she bolsters her troop numbers from the deceased, making the Horde despite themselves dependent on her. If Sylvanas can also rebuild her feared Assassins into something even MORE than they were before...the Hour of the Forsaken could indeed be at hand.
