Good to see you. * Player: Good to see you too, sir. * Herbalist: We had recently found something directly below our village, and we are destine to find out. * Player: Of course! What do you need help with? * Herbalist: Go and speak to Tyl. I think he's near the crevice. It's in the forest due west of here. Head west out to the forest and find Tyl. Speak to him.
