Ryan lived his life on Earth trapped in his own body. The doctors couldn't explain what was happening to him, but slowly, his body was crystallizing.

Fight, survive, adapt, and rely only on yourself. That is Derek’s creed and what's got him through the System Integration on Earth. Everything changed when the System came. Cute bunnies and beautiful butterflies became savage killing machines. Then the Invaders arrived with a single goal: to obtain ownership of this new habitable planet. War has raged ever since. None of this mattered much to Derek, aside from making living a little more perilous.

Adam isn't isn't even given the chance to lick his wounds after a deep betrayal before a mysterious force pulls him into into a new, fantastical world. He doesn't mind much.
