In the last hours of the War of the Shifting Sands, the alliance of the four giant dragons and the Night Elves were closing in on the core of the Qiraj Empire. The different insects of Silithus retreated in defeat, ending up in the Fortress of Ahn'Qiraj City.
But inside the gates of Ahn'Qiraj, there was a different group of giant insects waiting for them, a number that was unfathomable for the Kalimdor allies.
After going through an endless military campaign, the Kalimdor allies still had no way to defeat the Qiraj Empire and her various insects. They could only use some powerful magic to seal them up, and because of the flames of war, Ahn'Qiraj was now a pile of cursed ruins.
After thousands of years, the aggressive heart of the Qiraj was not softened by their restrictions. There was now a new generation of various insects who slowly emerged from their cocoon of a lair. The Ahn'Qiraj ruins were once again filled with different Qiraj insects.
