After wandering around for a while, you think you've found what's pretty much the only way out of here.
The howling is coming from this direction.
You keep walking, but the brick road abruptly ends. Your progress is quickly halted as the howling grows closer.
A nefarious WILD BEAST lurks deep in the shadows ahead.
Will you confront it?
Howling? a yellow brick road? This sound like a fairytale land to me...
tl;dr: Unfortunately, Nino and Five discover the howling is coming down the one and only path out. The beast is near, and some trees for some reason have been chopped way too high up on the 2nd image.
