The origin of storms

The Lotus Kingdoms are at war, with four claimants to the sorcerous throne of the Alchemical Emperor, fielding three armies between them. Alliances are made, and broken, many times over - but in the end, only one can sit on the throne. And that one must have not only the power, but the rightful claim. The Rajni Mrithuri stands as the chief claimant to the Alchemical throne now, but she and her empire remain a prize to be taken unless she gets an heir. She has her allies - her cousin Sayeh, a dragon, a foreign wizard, a fearsome automaton, and the Dead Man - but the throne has the final say. And if it rejects her, the price is death.
