The Harrowing: with a quirky twist?
Ever since Ruined King was revealed, I thought it would be kind of a cool, if not irrelevant and maybe slightly awkward project to take the "worldwide harrowing" bit and make it into a Guitar Hero offshoot, where instead of claiming souls being the idea, the Harrowing was a Pentakill tour and they were taking the world by storm with their metal.
Same plot, Thresh telling the Ruined King that the worldwide harrowing is gonna be a thing, just different context. It's music and fans instead of souls. Just a for-fun thought.
