Tell me what u guys think about a WoW fan story:

It's about two half-elves. A sister and brother. They are the offspring from the leader of the Blood Elves and a powerful female mage. They are both killed and the brother and sister seperated. The brother raised by orcs and the sister raised by Night Elves. None of the factions know that they are blood elves for they resemble more human charateristics. The brother grows to have a slavish devotion to the Horde and Thrall, the leader of the clans, orcs, and the Horde, has him learn how to fight like a troll, summon the spirits of the Earth Mother like a Tauren, summon magic like a blood elf, and learn knowledge from the Forsaken. The sister learns how to become a druid and eventually learns how to become a Paladin, however she does not have such faith in the Alliacne, but more in the Holy Light. The brother however begins to do quest for Thrall and begins to realize he has an addiction to magic and begins to experiment in the ways of the warlock. Prettyh much the rest is about quests the bro does and occasionally buds heads with his sister and in the end he ends up fighting for the throne of the Lich King.
What do u guys think?

I'd switch around the classes, but overall sounds like it could work. How about...

Eventually each begin to collect friends, and soon followers, and eventually small armies and then their own clan decades down the road.

Pedal to the metal on the EPIC WAGON!

WOOO!

Well, that was my future idea. The bro would lead the eastern Horde to take over the Alliance and the sis would lead the Elves and Draenei in Kalimidor
