Travel to the Chamber of Heart and commune with Azeroth.
Our world's dyin', <name>. Sargeras's sword has cut deep. Her pain is drivin' the elements into a frenzy! I can hear Azeroth's voice, but she needs more than her speaker. She needs her champion. Far below us lies an ancient titan vault called the Chamber of Heart. I sense she wishes tae speak tae ye there. Come with me into the chamber. It may be our only chance tae save her!
