The Rhine Maiden is a massive anti-Gnosis sonic weapon developed by Vector Industries and constructed on its three main flagships, Woglinde II, Wellgunde and Floßhilde (Flosshilde) as well as its corporate headquarters, the massive space colony Dämmerung. In Xenosaga: The Animation, the Dämmerung was shown firing the Rhine Maiden without any firing effect from the Woglinde II, Wellgunde and Floßhilde, though this may have been an oversight on the part of the animators.
