Dark Sirius is a lightless world, the third planet of a system in the Orion region. Deprived of any sun, it drives the villain Dark Nibiru to gather a force and march on Earth in pursuit of the Silver Crystal, hoping to make it their own star.
The world is defined by perpetual darkness, holding no sun of its own to light it. It sits as the third planet of a system located within Orion. The stage shows never actually depicted the place on set.
What gives the planet its identity is a hunger for light. Its people hold that the Silver Crystal once belonged to them and was stolen away, a grievance that shapes the ambitions of those who call the world home.
Because the planet lacked a sun, a figure named Dark Nibiru assembled a group and traveled to Earth to claim the Silver Crystal, meaning to turn it into a sun for their home. Although Dark Sirius itself never appeared in the musicals, it was mentioned several times and proved central to the plot of the show that referenced it.
