Elves of Evermeet
The Moon Blades are powerful artifacts created long ago by the elven nation to determine the rulers and nobles of the Elven Empire. There are about 300-400 blades in Faerun are and are only wielded by those that are deemed worth enough by the blade. These blades are often passed down from family after the previous owner has died.
Some of these wielders of these Moonblades are part of a special group for "the sad" Queen of evermeet which deal with special missions given from the throne and her council.
