Adventure Guide
''Aegwynn used this sacred temple of Elune to lock away the defeated Sargeras' avatar. She hoped it would remain dormant, buried deep within the earth, but the lure of power has continued to draw foul entities to this site. When re-entered the tomb, he tore down Aegwynn's wards and opened a doorway for the Legion to invade. Now, the fel army tears at the vault, hoping to reclaim their master's power.''

Encounters
After weeks of hard-fought battle, Azeroth's heroes at last enter the dark Tomb, but the Legion has been preparing as well... The lower reaches of the one-time Temple of Elune have been sealed away for generations, spawning unthinkable horrors. Aegwynn sealed away the defeated Avatar of Sargeras deep beneath the Tomb, but that fearsome husk now begins to stir... ''In the depths of the Tomb of Sargeras, Kil'jaeden appears cornered at last. Or are we just playing into the Deceiver's hands?''
