From chapter 1, I remember everything so here you go. This is everything that has been revealed from chapter 1 till 278 about what happened in the original timeline. The original timeline that Cordelia is getting flashbacks is from when Lucas is saved and she gets kidnapped. Cordelia turns into a demonic human, Lucas inherits his father’s sword. Wildlands are destroyed, Red Wind is an enemy. In search of power, Scarlet is possessed by a demon sword, making her one of the calamities, the crimson witch. Maximilian is the strongest. He is at the forefront of the fight. Leon turns on the humans. Demons invade the north from the wildlands. 3 months or so before the invasion (and about 1-6 months after Cordelia gets kidnapped, Count Bayer gives Jude a blue carp with pure ying to cure his condition during a festival. Jude then leaves to search for Cordelia. Everyone in the north dies except Jude. With a thread of reason left in him, Jude goes to search for his fiancee. The capital falls due to Devil's hands and then the elven forest due to Jabberwork and then the south. A hell gate is opened in the capital and the wildlands. Corrupted gods in the wildlands, a demon prince in the capital. The ancient dragon Malekeith reigns supreme in the south. Rise of the seven calamities. Scarlet is one of them. Events in the empire, Maximilian dies. Leon cannot be stopped. Empire is destroyed. The great summons begin. The fall of the empire marks the start of the war between the heavenly and the demonic. Jude inherits the 9 Heaven Doors. Fights Cordelia to the death. Loses everything. Currently the strongest in the Guardians of the Holy Cross and leader of the alliance between Lucas, Kasja, Adelaide(the only playable character not mentioned more than once. She's one of the 4 beauty kings of LotH 2 along with Cordelia, Jude and Maxi), and himself and humanity’s best hope at survival. Jude breaks down. The young god of the Guardians of the Holy Cross, Atelia, is dead. The whole world is ravaged by the war between the heavenly and the demonic. The concept of a nation no longer exists. Kamael is the only paragon alive. Jude begs the dead god to have a chance to see Cordelia again. That’s it. The more we see of the past, the sadder it gets for Jude. Humanity's strongest soldier is nothing but a kid who lost everything when he couldn't even fight for it. You really just need to read the bold ones for recap.
