Door of Night

A guarded portal in the distant West of the World, through which Morgoth was cast after his defeat in the War of Wrath. Its origins are unclear: according to some accounts, it was made by the Valar as a passage for the Sun, which would return into the World through the Gates of Morning in the east. According to others, though, it was made expressly as a gateway through which to expel Morgoth. The Door of Night was guarded by Eärendil, bearing his Silmaril aloft in his shining ship Vingilot.
