Physics of the Apocalypse 2

In the aftermath of the Apocalypse, humanity struggles to survive in a world newly introduced to mysterious particles. Preparing for the moment when Earth's planetary protections will cease and open the planet up to invasion by alien species, Liam and his companions transformed the Beacon, their sanctuary, into a fortress. As the last line of defense, they strive to train and empower the Beacon's residents, raising their levels and strength to withstand the impending onslaught. The coming days will be filled with battles, trading, and a lot of research on how the multiverse works and exactly what the Dominions are. Spearheading the efforts of humanity is... Jon. How? Well... there's only one way to find out.
