Dryad Entryway

The two oldest Dryads decided to root themselves at the edge of the Great Forest near where East City sprung up over the years. The two Dryads chatter away, to each other, about each other, and to anyone who wants to enter the Great Forest. Although there is nothing from stopping anyone from entering the forest wherever they want to enter (at least, most places), the two Dryads have made a name for themselves as The Entryway into the Great Forest.
Like a couple of old mates, they argue just as much as they don't. Yet they won't ever leave the other.
