From publisher blurb:
Few magical items are as timeless as the cloak of elvenkind. These magical swaths of fabric allow the wearer to pull the cloak around themselves and blend into the surroundings. This simple, yet useful magical has existed in one form or another for millennia, for nearly as long elves have called themselves civilized. Though the item is certainly humble and the property of the most common elves, and even gifted to the friends of elves, but the history and myth of these swatches of fabric mirrors the history of the elves themselves.
