Flight of the Red Court Refugees
Something is terribly wrong. All of the masters have been destroyed by some powerful spell. Even some of the other half bloods died. But you have survived - either you were too weak, or too new to the blood.
The call of the blood was too strong, and you have recently killed and fed for the first time completing your transformation into full members of the Red Court, maybe the last on Earth. The other supernaturals are hunting you, looking to erase your kind forever.
Then you had the dream. One of the Nobles somehow survived the cataclysm and is calling you to a new center of power - Prague in the Czech Republic. You start by traveling to Dallas, Texas where you find several other survivors.
Now you just have to figure out how to avoid the Wardens, the White Court, and all the other magical creatures out to kill you...
