Gundam Prequel Chapter

In AD 3524, Star Year 150, about 10,000 years ago, the colonial satellite named "Tevat" had a dispute with its affiliated space station "Canrea". Sky Island sent mobile suits to bloodbath Canrea, and the travelers and others were forced to take the Merofana to the earth. 500 Years later, the Integration Movement launched the "Terra Fall Incident" and knocked the colonial satellite "Tera" down to the earth, causing a large number of casualties. What secrets were hidden in these events? Did the Integration Movement really fight for power for the infected? Is Sky Island really to prevent the Abyss from invading Teyvat? Is the Fools' confrontation with Sky Island really for Teyvat? What is the meaning of the existence of "Gundam"? Is it a war? Or is it a possibility?
