In the previous chapters, the heroes have dealt with the aftermath of the Silver Storm and the impact it’s had on Emerald City. By this point, the heroes should have established themselves as the resident superteam, funded by supervillain-turned-entrepreneur Maximilian Mars. They’ve also just stopped a team of stormers from recovering the mysterious technology behind the Silver Storm from a scientific research station while also dealing with the Brande Management forces that were protecting it.
It turned out that there was something beneath the oil rig, something that Brande Management didn’t know about. A spacecraft rose from the depths, collapsing the station in the process. It broadcast a message about humans interfering in events that they could not comprehend and that it had a mission to fulfill. The spacecraft then disappeared.
