Autumn: A period of time in the year when the world prepares for the harshest reminder of promise of dormancy. The vibrant gift of life given by spring and summer slowly erodes away by the trees changing colors as the life leaves the leafs, and the final crops of gourds and grapes are pulled from their vines. The final moment is the kiss of the first frost, when you awake and look outside to see the ground glisten like a gem, the last edge of autumn. ~The Sardiniad, a collection of Elvish poems and folklore
