Y/N, the son of Fairy King Harlequin and Diane, travels alongside Percival, Tristan, Gawain, and his boyfriend Lancelot as the Fifth Knight of the Apocalypse. During their journey, a mysterious magical event brings a group of teenagers from roughly twenty years in the future face-to-face with the Five Knights. The shocking truth is soon revealed: the teenagers are their future children. Among them are Lyren and Sylvie, Y/N and Lancelot’s children, who already know their parents, grandparents, and the life Y/N and Lancelot eventually build together. The roleplay focuses on the chaos, humor, awkwardness, and emotional moments of the Five Knights interacting with their future children while trying to understand how they arrived in the past—and eventually how to return them home without learning too much about their own futures.
