Jack Mitchell knows he won't survive the impact of the massive asteroid hurtling towards Earth. He's not one of the handful of lucky lottery winners scheduled for rescue. But he did luck into a NexGenVR capsule, which means Jack can risk a one-way trip to the world of Viridan Gate Online (V.G.O.), an ultra-immersive fantasy role-playing game. Taking that leap of faith, though, means permanently trapping his mind in the game and killing his body in the process.

With a cataclysmic asteroid careening toward Earth, the VRMMORPG project Viridian Gate Online has become more than just a game, and Abby thinks her boss, Robert Osmark, wants to be more than just its founding father.

Alan Campbell thought he'd gotten his dream job working on a revolutionary VRMMORPG with Osmark Technologies, until the project was canceled. He has one weekend to dive into an untested world full of intrigue, violence, and corruption to prove that Viridian Gate Online works, but the AIs running the game have their own plans for his soul. Set a year before the events of Viridian Gate Online: Cataclysm, Viridian Gate Online: Nomad Soul takes you back to when VGO was just a game, or so it seemed.

October, 2042. In two weeks, the world will die, murdered by a nine-mile-wide, extinction-level asteroid. And Robert Osmark—billionaire and savvy tech-—couldn't be readier for the fiery apocalypse. Unlike the shortsighted masses, he's been diligently preparing for this day from the moment the asteroid first appeared. Through his relentless efforts, digital salvation now awaits anyone bold enough to take the leap and permanently transition into the brand-new, ultra-immersive, fantasy-based VRMMORPG, Viridian Gate Online. And Robert Osmark will lead this new world he has created.

The end of the world is not such a bad thing for Russian weapons engineer Vlad Nardoir. Really his world ended six months ago when his wife died, and ever since then, things have been downhill. Soul-crushing medical debt. Favors to the Russian mafia. Now, asteroid. For Vlad, this is life in a nutshell. But, in a wild twist of fate, he has found a way out. A chance to start fresh in a brand-new ultra-immersive MMORPG called Viridian Gate Online.

The End is Coming. An extinction-level asteroid is cannonballing toward Earth. In humanity’s final hours, a lucky few earn a one-way ticket to the brand-new, ultra-immersive, fantasy-based VRMMORPG, Viridian Gate Online. Making that leap of faith might mean survival, but it comes with a steep price tag: “Travelers” will forever be stranded as digital avatars inside a fantastical world filled with vicious monsters, all-powerful AIs, and cutthroat players. Let the games begin....

Dr. Liset Chen vowed to save her world from the Darklings' influence, but when divine will directs her to Ankara and the Fighting Pit of Kar'Kun—a coliseum that pits the Priest against monsters and other Travelers alike—she must win the tournament and successfully clear a dungeon rumored to be a gateway to Morsheim itself . . . one no team has returned from. With her lover on the rival team and only one respawn left, Liset must prove her conviction, leadership, and faith are enough to seize this last chance to eliminate a source of Darkling power, even if it risks her own damnation.

After rescuing a holy relic from Darklings, Liset the Blessed learns no good deed goes unpunished. The Temple of Areste has given her a day and a half to make a choice: be excommunicated for turning in the quest item or excommunicated for stealing it. Either way, she risks losing her hard-earned class as a Priestess of Gaia, and with it, her ability to heal the people of Viridian Gate Online.

Silas is inducted into the System, becoming the last in a long line of Earth's "forerunners." The rewards are great, but the danger is greater. We are not alone in the universe. The fate of five worlds hangs on how their forerunners perform. Will Silas have what it takes to win Earth a place in the multiverse? Or will Earth become another mining world stripped of all resources and left a barren husk floating in the cosmos?

Multiverse Z came knocking, snatching all the humans from Earth to integrate with their game-like realms of magic. No warning. No tutorial. It's an instant transition where eighteen-year-old Joey Eclipse is thrust from his relaxing night playing video games to a stone room with two doors. There's nobody but him. The system messages asking some cryptic questions: [Adventurer or Commoner?] [Greatness or Steadiness?] And more. Joey made his choices, choosing the path of a Great Adventurer, a limited and special category. A unique profile is designed for him.

After Lucas dies during a freak explosion, divine intervention sees him brought back to life with the power to control a new dungeon. There are just a couple of issues: his old body is bound to his dungeon, and the craziness of what he thought was his final act is only getting weirder. When he sees newbie adventurers entering his dungeon, though, he decides to help them survive and complete their quests. After all, adventuring is a process, and someone needs to guide the rookies.

Ominous obelisks land on Earth with a single message: Join the games to give humanity a fighting chance to survive... Or roll over and die. Too bad for them, Warren isn't the rolling-over type. Cancer may be kicking Warren's a$$, but he's not about to let aliens destroy his home and everything he loves (which is mostly just his dog, Buck). Besides, what does he have to lose? Better to die with sword in hand, bleeding out from a head wound than in some hospital bed...

Unbeknownst to him, Ray is about to partake on an adventure filled with magical beasts, warring factions, and a leveling-up system out of this world.
