Forum:WHERE would the Sylvan Glade be, storywise?

I know how to GET there, I just don't know where it would be located STORYWISE. Is it another dimension? Is it a pocket dimension? IS the tree some form of tunnel to somewhere nearby? If so, why can't you just hike to the Glade? Is it surrounded by cliffs or something? Is it connected to the Mystical Magic Bean Portal Tree in anyway?
