This quest is not available in game.
Ysiel Windsinger wants you to look for signs of Cenarion Expedition Druids near the entrance to Coilfang Reservoir in Zangarmarsh.
I sent a small group of our druids to investigate the drain you discovered inside of Serpent Lake. They were expected to return shortly after. Needless to say, they did not.
You are amongst our most capable allies; I ask you to seek them and find out what became of them.
You will also receive:
- 1,100 experience
- 6 60 (if completed at level 90)
- 10 reputation with Cenarion Expedition
