Arknights Animation: Prelude to Dawn

Terra, a land plagued by unexplained natural disasters, has led to the creation of mobile cities as people seek refuge. The aftermath of these catastrophes has left behind a valuable resource: Originium, which fuels rapid technological advancement. However, this progress comes with a dire cost: the spread of Oripathy, a deadly disease that causes the infected to crystallize and become a perpetual infection source at death. As a result, those with Oripathy are subject to persecution, prompting marginalized groups to rise up against their oppressors.
