Okay. Set up for a superhero campaign of sorts. A villain team goes full terror mode on a public building ..maybe a theater, maybe a library, and sets up to collapse and kill everyone in there. Said villains are clearly okay with brutality etc, most wanted for at least a few deaths. Among the building's otherwise normal folks is a bored being, almost Q like, who could stop this easily but isn't sure why he should bother. Now either a superhero or one of the folks there changes this cosmic beings mind just enough to get him/her/it interested. The Authorities fail to save the building or even trigger the trap causing the building to collapse. (TBC)
