Starkiller Base was essentially the Death Star on steroids. The First Order converted an entire planet into a mobile battle station by hollowing out its core, arming it with a superweapon that consumed suns as a power source and could destroy worlds with a single shot. It's easily the most formidable superweapon in Star Wars history, even if it did suffer the same fate as the Death Star, destroyed by the Resistance. But whereas the history of the Death Star is well known, Star Wars hasn't really explored how Starkiller Base came to be.

The latest episode of Star Wars: Resistance, "The Core Problem," has finally begun to answer that question. It's set immediately before the events of The Force Awakens, and sees Kaz and Poe Dameron head out to the Unknown Regions to investigate First Order activity. Kaz has been studying the map he stole from the First Order in "The New Trooper," and he's noticed something strange that needs to be checked out. When Poe and Kaz arrive in a remote star-system, they're horrified to find destruction on a galactic scale.

As confirmed by Kyber Crystals, which were key to the development of both Imperial and First Order superweapons. But the First Order's tests didn't stop there; the system's star has disappeared, presumably consumed by the attempted firing of a Starkiller Base weapon. It's clear the First Order tested the superweapon at least once in the Unknown Regions, depleting a star in a system they had no further use for.
