"Tyche (/ˈtaɪki/; Ancient Greek: Τύχη Túkhē, 'Luck', Ancient Greek: [tý.kʰɛː], Modern Greek: [ˈti.çi]; Roman equivalent: Fortuna) was the presiding tutelary deity who governed the fortune and prosperity of a city, its destiny. In Classical Greek mythology, she is usually the daughter of the Titans Tethys and Oceanus, or sometimes Zeus, and at this time served to bring positive messages to people, relating to external events outside their control.[2]
