Day of Octagon

"Octagon Lives."
Set after the events of The Resistance Protocol, Tales of the Scattered, and Tales of the Numinous, The Core heroes have went there separate ways, on about their individual business. Yet, they will be united once more when a threat arises from another realm and even sooner when the rise of an artificial-intelligent force known as Octagon sets out to transform the world into a land of only machine and digital.
