Although the events started when Corvus marched into the formerly Corvun-controlled South Corvus, it was only a mere match that lit the powder keg. Antares’ emperor, Kalvin Tau was a staunch enthusiast of the ancient Libran Empire, an entity which used to rule the entirety of Forma before its collapse. Kalvin Tau believed that if all the people were united under one ideology, it would more or less end war. He also believed that Centaura would constantly be in conflict because there were multiple empires competing with each other; if only one empire remained, there wouldn't be war. After his Death his Son, Aran Tau, Took his place as Emperor. As the revanchist Corvus requested Antares aid for annexation, Aran Tau and his son, Kaden Tau, would seize the opportunity and thus, Antares began to act upon their ambitions in 1911, with the invasion of Cetus on the side of their Corvun allies. During Antares' invasion of Vega in 1914, riots and protests broke out amongst the Grusan populace for them to support Vega. Their pleas were ignored and the protests were harshly shut down, sometimes violently. Thousands of Grusan volunteers would defy their government and join the Vegan army. After Antares successfully conquered the two nations, they saw a unique opportunity to build strong support in the region. Members of the unpopular royal families were executed, imprisoned, or banished, and both regions were united into 1 unified body as an Antarean puppet, Skorpii Grusii. A popular unification supporting activist, Xavier Navarro, was appointed as governor, and the state was allowed to maintain most of its cultural identity. Some Grusan forces would also see action as reinforcements in the later phases of Antares' Columban campaign.
