Second Great Asian War
From YATA Wiki
Emperor Li Xiang of Sizzle died of a stroke after many years of rebuilding Sizzle's position to the world stage, leading to his 13-year-old son Chonglin Xiang being crowned as the new emperor. Lineland, despite acknowledging that the two hated each other, offered to launch a joint invasion of Sizzle in order to destroy their common enemy.
