In the distant north of Middle-earth, between the far reaches of the Blue and the Misty Mountains, lay a wide icy bay of the Great Sea. This was the mighty Icebay of Forochel, which extended far into the coldest regions of the north of Arda. To the north and west, the bay was sheltered from the Sea by the curve of the Cape of Forochel.
Despite its freezing climate, tribes of Men lived around the shores of the Icebay. Far back in the Elder Days, these were the people known as the Forodwaith, but by the Third Age, their descendants - the Lossoth - occupied the northern wastes in their place. Their main settlements were along the sheltered Cape, but they wandered far and wide around the Icebay, even venturing as far as the Icebay's southern coasts.
Forochel will be added in Book 13: Doom of the Last King.
