The Darnussia–Keymon War,[1] also known as the Heinovich War (Darnussia), and the Great Patriotic Defensive War (Keymon) was a war between the Second Darnussian Democratic Republic and the Democratic People's Republic of Keymon that also involved the Holy Luthori Empire, Rutania, and Malivia on the side of Darnussia; and Hutori on the side of Keymon. The conflict started over disputes of Keymon harbouring Lusitânian terrorists by Darnussia, and Keymon's subsequent declaration of war. After a nuclear bomb was dropped on Merenbürg, public opinion turned against Keymon, and Keymon soon found itself invaded and occupied after a brief conflict. Approximately 200,000 people lost their lives in the conflict.
