Avin's Cliff is the cliff at the edge of town that seperates Avinville from the Blank Woods. It is a cliff that hangs off the edge of a slope with a large oak tree leaning on it, with several reeds growing down the bottom. The cliff is a popular couple's spot, a place to think, and just a good view of the forest. There is a house nearby on the hill's slope, where Sonic and his family and roommates live. The cliff is a very important part in the series, for it appears in everything and has been the source of some great things.
