A Star Goes Out

Far coreward of the Empire, beyond the RUR Workers-State, an apparently healthy G-class star has recently dimmed and winked out. Perhaps this is a Dyson Sphere. Or its close cousin, a Matrioshka Brain - one of the technologies that the RUR Workers-State is forbidden by treaty to construct.

Or is it something worse?

The Empire has extensively cataloged all of the dark legends about the Bright Core at the center of our galaxy. These stories have been carried Rimwards by refugees for generation after generation.

Who will investigate?

Thanks to Juan Ochoa for this idea!
