Ysera's Tears

Good to see you again, $N! You were exceptionally efficient in completing the last task that I offered you. Perhaps you would be interested in another?$B$BTo 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.
