Jessera of Mac'Aree at Blood Watch wants 2 Ysera's Tears.
Good to see you again, [player]! You were exceptionally efficient in completing the last task that I offered you. Perhaps you would be interested in another?
To the northeast lies Wyrmscar Island, home to a rare species of mushroom known as Ysera's tear - named after the green dragonlings that inhabit the island. I only require a small sampling of the mushroom, but I must warn you that the denizens of the island do not welcome visitors. Tread carefully.
