The natural disasters of the undead have completely turned Lordaeron and Quel 'Salas into places full of poisonous epidemics. Only a few small-scale alliance resistance forces are still alive. One of them is mainly composed of high elves, and their leader is the last member of the Rising Sun Dynasty, Prince caces. As an excellent mage, Carl carefully grew up in the near-destroyed alliance. The high elves are very sad about the fall of their home. In honor of their dead compatriots, they changed their names to blood elves. When the blood elves struggled to contain the attack of the immortal natural disaster, they suffered great pain because they left the source of strength-the sun well. In order to alleviate his innate thirst for magic, Carl did something unimaginable: he accepted the help of their ancestors of high elves and joined Illidan and his Naga army, hoping to find a new source of magic power. The remaining alliance leaders condemned the blood elves as traitors and expelled them forever. Desperate Carl and his blood elves had to follow Illidan to Outland to help him deal with Warden Maiev. Maiev once captured Illidan, but was defeated by the blood elves and Naga, and Illidan was liberated again. Illidan, based in Outland, rallied his forces to launch a new round of attacks on the Lich King and his Iceberg fortress.
