Anthony 'Tony' Michael Dominic DeSaxe IV, also known under his family's traditional moniker of Hades, is one of the Kings of the Four Legendary Kingdoms.
Anthony DeSaxe was born in 1960 as a royal. He eventually became a member of the Kingdom of the Underworld (which did not include his French homeland) as part of the ancient group known as the Four Legendary Kingdoms. Because of his membership in the Four Kingdoms, Anthony was taught about the true history of mankind, as well as learning of the five trials set by super-ancient beings to test humanity.
Following his father's death, Anthony became the patriarch of the DeSaxe family, and inherited $2 billion from his father. In a few short years, he was able to turn this into $12 billion, thanks to good business deals in two ventures; mining and shipping. With the latter, through his company of DeSaxe Shipping Co., Anthony both constructed and deconstructed shipping vessels.
While the outside world assumed he was just a private and wealthy corporate owner, Anthony also took over as the King of the Underworld, being the fourth of the DeSaxe family to do so, and took on the King's traditional title Hades. His domain, though being the smallest of the Four Kingdoms and comprised primarily of just India, also included the vast meteor crater which housed the Underworld, which had been the setting for three previous Great Games of the Hydra and several myths that the world had come to misinterpret.
As the Underworlds' ruler, Hades also became the master of the enslaved race of Neanderthals (referred to mostly as Minotaurs due to manipulation of the Four Kingdoms over the millenia) that resided there. Hades, though firm in his treatment of them, was treated them more fairly than most of his predacessors, and became friendly with the Minotaur King, Minotus. Hades' most important asset in the Underworld, however, was the great antenae which would only activate following to the third trial set by the super-ancient beings.
During the late 20th century and early 21st century, both the Kingdom of Land and Kingdom of Sea used their agents to undergo missions to complete the first two of the five trials, the Tartarus Rotation and the Return of the Dark Sun. Since information and components relating to the first two trials had become lost over the centuries, Hades made no effort to take part in either mission, believing that if humanity had lost the knowledge for completing the trials and failed as a result, then they did not deserve to exist. In the end, though, both trials were completed.
Sometime between 2010 to 2011, Hades's wife died.
In 2016, the Star Chamber within the Underworld opened, allowing the nine Golden Spheres to be retrieved. As this heralded the third trial, the Diverting of the Hydra Galaxy, Hades alerted the other Kingdoms of the development, with the Great Games of the Hydra set to begin within the next month. Having been anticipating that the Chamber would open, Hades selected his four champions for participation in the Games; his son Zaitan, Sachin Singh, Wasim Nasiruzzin and Ravi Mano.
Prior to the commencement of the Games, Hades told Minotus that he would allow his people their freedom once the Games were completed.
- Hades is the first main antagonist in any of Reilly's novels to change his ways and join the protagonist (not including Jack and Wolf's brief alliance during The Five Greatest Warriors due to Wolf's continued actions against his son later).
