Before we even get started with this weeks KYL, let's take a look at parts 1 and 2 of our War of the Ancients roundups. Now that we've done that, we'll open up this post with an attempt at a succinct overview of the war and the difficulties inherent to discussing it.
Queen Azshara and her Highborne (quel'dorei) became arrogant and obsessed with the magical power of the Well of Eternity, a font of magical power the size of a massive lake that dominated the ancient single continent of Kalimdor. The wall was the source of all magical power the kaldorei (night elves) used in their world spanning civilization and far, far more as well. Created by the Titans, the Well's incalculable power was so vast that it called across the vast distances of the Great Dark Beyond to the fallen Titan Sargeras, who sought to use the Well's power to instantly enter Azeroth bodily and commence the annihilation of all the Titan's work in creating it. Azshara, whether through domination by or love for Sargeras, sought to aid him, even though it would destroy her own people. The native forces of Azeroth, the Dragonflights and nigh-immortal Ancients, rose to prevent the Burning Legion's destruction, but due to the treachery of the earth aspect Neltharion, they ultimately failed.
