Also called "Dugradigdo". The Dark Lord of the world where Volfied is the Dragon God in the Slayers multiverse; by this token, he is a counterpart of Ruby Eye Shabranigdo and more or less one level down on the hierarchy from the Lord of Nightmares. By the time he makes it into Ceipheid's world, Dark Star takes on the form of a large thing with many legs and a long head. Since he is one of the great Dark Lords, Dark Star has some power over chaos, which is essentially nihility in the Slayers world.
There are five "weapons" associated with Dark Star:
- Gorun Nova (the Sword of Light)
- Ragdo Mezegis (a lance or spear)
- Nezzard
- Bodigar (an axe)
- Galvayra (a bow)
Gorun Nova and Ragdo Mezegis were used to open the interworld portal that summoned Dark Star; Nezzard and Bodigar were used to bind Dark Star's power. Galvayra was used to smash Dark Star. This is how it works, in theory. Actual events were somewhat different.
The anime Lost Universe is also an interpretation of events in the Dark Star world.
