The Nightmare Treant is sneaking a peak over chatlog. He doesn't know who you are. He doesn't know what you want. If you are looking for ransom, he can tell you he doesn't have money. But what he does have are are very particular set of skills; skills he has have acquired over a very long career. Skills that make him a "nightmare" for people like you. If you let his daughter go now, that'll be the end of it. He will not look for you, he will not pursue you. But if you don't, he will look for you, he will find you, and he will kill you.
