It's been almost four hundred years since the bombs dropped, since the toxic jungle currently devouring the world took root. Tubbo has it good in L'Manberg with his semi-reluctant older brother figure, his shy amnesiac boyfriend, and all the pie he can eat. So when he finds a guy his age in an ancient vault, and hears the rumors about Manberg supposedly building a weapon capable of destroying cities, he isn't sure what to do. Tommy, however, isn't exactly thrilled when he wakes up four hundred years later than when he fell asleep with no memory of how he got here or how the hell he got strong enough to effortlessly rip a door off its hinges. A lot of the people he woke up to don't seem to want him around, and soon enough he finds himself in a terrifying race against time, struggling to put together the scattered pieces of his past before a madman blows the planet to hell again. Tensions are rising, the jungle is spreading, and the fate of the world rests on the shoulders of a handful of uncooperative individuals with enough collective trauma to make your average therapist have a breakdown. What could possibly go wrong?
