Description
The rutaani who attacked Silvermoon come from my homeland, Harandar. This Lightbloom infection is new, however.
The time has come for me to return to my people. I will face their judgement, and explain my actions.
If the Lightbloom has spread, I must warn my people of the danger. If you're willing to join me, I will take you and your insistent friend through the rootways to Harandar.
Let me know when you are ready to go.
