William IV

Emperor William IV of the Tyretian Empire, Kingdom of Arcadia, and Solitude, Duke of Sicorides, was the last member of the Royal House of Deisezo. 
William's mother died in childbirth, and his father vowed to never remarry. At the age of 6 he was betrothed to Princess Evelyn of Gretia, and they married in 1271.
For much of their early marriage the two were apart, revolts in Arcadia took up much of William's time after he succeeded his father, and Evelyn was preoccupied with ending her father's costly wars, which she only achieved after he died. After two miscarriages, Adelaide was born in 1285.
William IV reluctantly supported his wife's war against the Empire of Kordowyn.
