Novayan–Roman War

The Novayan–Roman War, also known as the Unity Pact-Roman Empire War, the International Senate-Roman Empire War and the War against the Roman Empire, is a military conflict taking place on Earth after the Novayan Commonwealth, Saiyanese Federation, Order-State of Merdina, Novikan Republic and Selanian State were brought there by the accidental activation of an unknown device called the "Ascension Device".
The war, already in full swing, expanded when the Unity Pact, composed of the five Armanyan countries and after being brought to Earth, immediately launched a series of campaigns against the Roman Empire and its ally, the Pony Republic of India. The campaigns saw the invasion and occupation of the Roman Empire's overseas territories, the Pony Republic of India and the Roman Empire proper. Novaya and Saiyane, despite respectively a hereditary military dictatorship and a hereditary plutocratic oligarchy, established bundeskommissariats from the former Roman colonies, which, believing the Unity Pact to be no different from the Romans, experienced development in the forms of reforms, public works projects, and modernization, fostering socioeconomic, sociocultural and sociopolitical prosperity. The ponies of India resisted efforts of modernization until the introduction of several angels, demons and youkais, shattering the ponies' religion in its entirety.
Meanwhile, the leaders of the Unity Pact and the International Senate organized a tribunal against Malty Melromarc, who is now alone after many aristocrats, politicians and military leaders defected to the coalition upon sensing the wind turning against the Roman Empire.
