I was about to post to this thread with N2! It's just dreadful. It's a railroad, which isn't necessarily a bad thing (the GAMMA WORLD module Famine in Far Go is a railroad, but an awesome one). But The Forest Oracle is a boring railroad and, as you point out, has some truly dreadful flavor text. It stands as the only D&D/AD&D module I have never finished.N2 the Forest Oracle for D&D is one of the worst I've ever ran. I don't know why the NPcs were not singing or joking but the module makes sure I know they are not.
"A group of seven men approaches. They are following the road east, and are making good time, neither tarrying nor running. Their faces are expressionless. One is dressed as a cleric of some sort, and another is dressed as a traveling drummer. The others could be peasants or serfs going from one location to another for the harvest season. Each carries some sort of weapon. It is plain that they are not soldiers by their haphazard way of walking. They do not seem to be joking loudly or singing as they advance. "
