Derek Carter never asked for a System, an apocalypse, or the pressure of being humanity’s so-called “last hope.”He was just trying to survive the daily struggles of being an orphan in Paleview City—dodging bullies, scraping together meals, and lying his way into school. Life was already hard enough.Then, one day, a blue screen pops into his vision:[Warning: The world is doomed. Try not to die.]Yeah, great. Just what he needed—cryptic doomsday messages and no instruction manual.Now, monsters are creeping into the city, reality is unraveling, and Damien’s “legendary” starting stats are barely above zero. The System promises him power, but there's just one tiny problem—he’s never won a fight in his life.Armed with sarcasm, questionable decision-making skills, and the sheer refusal to die, Damien is about to embark on the worst (and possibly last) adventure of his life. Because if the world really is ending… he’s at least going to make it someone else’s problem first.After all, heroes are overrated—survivors get to tell the story.

Elias and friends thought it was just a storm, everyone at Avonside University did, but when the clouds cleared and the sky was revealed again, they were met with a strange sky. Gone were the city lights and everything beyond the limits of their campus, replaced by a mountain wilderness. Elias is further swept away when he is torn from his friend's grasp and transformed beyond recognition. Will the newly dubbed Ryn find her way back to her friends, and or will she return to Avonside to find it ransacked and destroyed by the strange and magical forces that inhabit the new world?
