The Adumari Coalition was a confederacy of Adumari states opposed to Cartann, the largest Adumari nation-state, whose perator Pekaelic ke Teldan tried to forcefully form a world government with Cartann as its head. The first states which rejected his idea, were conservative governments of Halbegardia and Yedagon Confederacy, which itself was a group of nation-states with Yedagon as its main representative. Later Thozzelling and Tetanne and probably other small states joined this coalition.
