Characters/Pairing: Lúthien, Melian
Disclaimer: Tolkien's the genius, not me.
It happened almost overnight: mists appeared to twist through the trees and confuse those unfamiliar with the forests of Doriath. No one could get through without the knowledge and permission of Queen Melian, and so Doriath was cut off from the plains to the south and east, the mountains to the north, and the rivers flowing west to the sea.
Lúthien wondered at first why such a Girdle was necessary, until something dark threatened the northern borders, and stories reached them of a dark, hungry terror in the mountains.
There would be no more peace in Beleriand beneath the stars.
