At an area of 10,000 km² (the size of the country of Lebanon), it is so large that it could be considered an artificial planet. The interior of which is a colony beyond imagination-- it is the nucleus of the entire group which included all the of the relevant enterprises under its umbrella, including the establishment of the residences of all the of the company employees belonging to it, and it is fulfilling all of the important municipal functions of that kind of daily living.
It carries on it the Rhine Maiden, a devastating large-scale sonic weapon and millions of torpedo tubes.
Dämmerung is German and means twilight in English. The name is most likely derived from Götzen-Dämmerung, a philosophy book by Friedrich Nietzsche. Götzen-Dämmerung means "Twilight of Idols" and itself is a pun derived from the opera Götterdämmerung ("Twilight of Gods") by composer Richard Wagner, a close friend of Nietzsche. In Norse Mythology, Gotterdammerung is another name for Ragnarok, the end of the Earth. At this time, the Gods engage in a final conflict with various opposing forces of evil, and the entire world will be destroyed by fire, sinking into the sea to rise again as an ideal world full of only goodness, where Gods and men live together in harmony.
