Not long after the fall of Aquila, Antares begun an offensive in the northern regions of Vega (which ended in a disaster) tbis started the Vegan Campaing

In the early months of the campaing, Antares struggled to advance. This was due to Vega being just as modernized (military wise) as Antares, aswell as having bullet proof medival armor which protected the soldiers. But what made the Anterean advance near imposible was a giant fortified wall that streched from the northernparts of the Murus Plateo donw to the coastline.

After another major defeat in the Murus Plateo, Antares developed a new plan, coastal invasions. Due to Vega not having a navy (or even coastal defenses) the Antereans invaded the vegan island and went behind the wall, trapping most of their army and capturing most of the nation (including their capital) by 1915, most of the nation had fallen. With half their army decimated and most of their tanks, factories and planes having been captured, what remained of the vegan army tried to stop the Anteran advance using leftover pieces of armor and defenses that were meant to be used agasint Grusa. After a major defeat in mid 1915, what remained of the Vegan army fleed to Grusa and joined the grusan army to continue the fight
