Context paragraphs:
Lake Galvė: Lake Galvė is a lake in Trakai Lithuania.  It has 21 islands, and one of them houses Trakai Island Castle.  Trakai Peninsula Castle is located on its southern shore.  There are ruins of the little Orthodox church in Bažnytėlė Island.  Trakai was the capital of the Grand Duchy of Lithuania from 1321-1323 before moving to Vilnius.  The lake and most of the other lakes surrounding the castle and city have myths and legends connected to them, of which most contain a tragic love story.  The lakes and castle are therefore also said to be haunted.

Karakaj: Karakaj (Serbian Cyrillic: "Каракај") is a town located 2 km north from the city Zvornik in Republika Srpska, Bosnia and Herzegovina, on the Drina River, it has also the border checkpoint with Serbia.  The word "Karakaj" comes from Turkish word which means "dark stone".  The dark stone is located near the bridge in the center of the town, and there are lots of legends and myths about this great art of nature.

Griggstown cow: For thirty years there had been a legend of a "ghost cow" that wandered the areas around the Millstone River floodplain and Griggstown.  The cow was seen many times but only on foggy nights or other times of poor visibility, and many tales were told by local hunters and hikers along the canal path.  No spoor or tracks were ever found.  Some fuzzy photographs were even taken, but they were all inconclusive.  At the time area was mostly suburban homes and open fields, and the canal was now a state park and walking trail so reports of a lone feral cow wandering a suburban park for decades were greeted with suspicion by local authorities.  The cow became known as a sort of "Loch Ness Monster" of New Jersey and believed to be a myth, much like the Jersey Devil.

Kleodora: In Greek mythology, Kleodora was one of the prophetic Thriai, nymphs who divined the future by throwing stones or pebbles.  She and her sisters Melaina and Daphne lived on Mount Parnassus, were Delphi is located and was loved by Poseidon.  With Poseidon she became the mother of Parnassus.  In myths where demigods have two fathers the other is listed as Kleopompos.  Parnassus is famous for creating a method of telling the future by using birds and founding the main city on Mt. Parnassus.  Her father was the local river-god Cephissus of northern Boeotia.
