With the release of Patch 10.2.7 Dark Heart, the final chapter of Dragonflight's storyline is available to play. We played through the questline to bring in all the details!
WARNING: Patch 10.2.7 Dark Heart Story Spoilers in this post!
The Dark Heart questline starts the moment you first log in for Patch 10.2.7. Khadgar will send you a message telling you to go to Dalaran to meet him as soon as possible.
