The Phiyi Tower is a skyscraper located in the state of Acheron on Charon III. Designed by Alia De Monde, it was constructed to inspire hope in the people of Acheron after a deadly 2934 earthquake destroyed many historical and beloved buildings. Though it is now considered a masterwork of Supermodernist architecture, at the time, its construction was costly and complex. The project also endured numerous protests claiming mistreatment of laborers.
