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?

Two years ago, Manberg fell, and the jungle flourished in the wreckage. Quackity is forlorn. He's been trying, he really has, but everyone he's loved has left him; everything he's built has fallen apart and for the millionth time, he's alone. But when he goes to visit an old friend's grave one last time with plans to put a bullet in his own head, he finds something... unexpected. Tommy has questions. After he was exiled from L'Manberg for a crime he didn't commit, there's been no contact whatsoever from the Badlands. Still, he doesn't want to meddle, because he has it good at Philza's anarchist commune and for once, his life is somewhat stable again. However, that all changes when he visits an old enemy, and gets a lot more than the answers he wanted. Tensions are rising, the jungle is changing, and once again, the fate of the world rests on the shoulders of a handful of uncooperative individuals with enough collective trauma to give your average therapist a breakdown. What could possibly go wrong? --- Or, the loose ends of Where Is Your Rider lead to chaos that only the wrath of gods can rival.
