Ruined Dyson Sphere
The "Ruined Dyson Sphere" event in Stellaris — flavor, choices, and how to trigger it with the event console command.
Ruined Dyson Sphere

We have encountered the remains of an enormous space structure in …, encompassing the system's primary. Our scientists theorize that this may have once been a functional "Dyson Sphere" - a megastructure designed to harness the power of a star. It is obviously no longer operational, with its hull having sustained critical damage from an unknown type of energy weapon. Of note are also the large debris fields surrounding the sphere. Although the megastructure itself is ancient, much of the debris in the system appears to be significantly younger. Most of it seems to originate from two distinct battle fleets that pummeled each other into oblivion, possibly in a war to decide ownership over the shattered sphere at some point in more recent galactic history.
The command below will trigger the "Ruined Dyson Sphere" event in Stellaris:
