Black May

Black May was the name given to a series of nerve agent attacks orchestrated against the St. Ives Compact during the brief St. Ives-Confederation War in 3062-3063. The attacks were ordered by Kali Liao, the sister of the reigning Chancellor, Sun Tzu Liao. Because of the implications of releasing nerve agent during a war, Sun-Tzu Liao gave the Compact full information that helped to keep casualties from the predicted millions down to below 100,000 people. As a direct result of the attacks, Kali Liao was imprisoned within the Confederation, and her cult of Thugee assassins were supposedly disbanded.
