In the first book of this Lovecraftian dark fantasy, an ordinary man finds himself in extraordinary circumstances—and responsible for the fate of humanity.

Walter was a petty crook, struggling to make ends meet, when he was suddenly abducted to another world. One of many people from Earth drafted by aliens to participate in "the trials" in order to gain "ascension," he must now endure hazardous environments and hostile creatures, strengthening his physical and mental skills to superhuman levels.

Fortunately, Walter has been gifted an Absolute Luck System, granting him the uncanny ability to achieve the statistically best possible result in any situation. Between this new AI and his quick thinking and improvisation skills, he has been deemed a lord arbiter for the inhuman monstrosities behind the trials and is sent to investigate a mysterious temporal anomaly. "Posing" as a human, he convinces the aliens that he must engage in the trials to uncover the source of the glitch.

But Walter is walking a very thin line between working undercover as a Xollon—a fierce alien race involved in running the trials—and helping humanity survive. And as he battles zombies, joins a band of superpowered warriors, and assumes the identity of a god, both he and his AI will face a soul-devouring darkness that even their luck cannot evade . . .
