What is the definition of Edgewood?

Edgewood is like that peculiar spot on the world where the trees are so close together they form an invisible curtain, and the sunlight barely peeks through, leaving just a faint shadow at the edge. Imagine it as the crossroads of nature where the line between forest and wilderness is so blurred it's almost a secret society meeting place for trees.
