Ashen-Shugar/Tomas is a fictional character from the Riftwar Cycle series of books by Raymon E. Feist, which take place in the fictional world of Midkemia. According to the books, Tomas, a teenager from the city of Crydee, was gifted a set of gold and white armour by the ancient golden dragon Rhuagh, after stumbling upon him in a deep abandoned dwarven cavern. The armor contained the bound essence of the Dragon Lord, or Valheru, Ashen-Shugar, the Ruler of the Eagle's Reaches, whose power was contained within the armor, imbuing Tomas with his former power, melding them into one super-powerful mortal entity. This union, seemingly improbable due to the thousands of years between the lives of Ashen-Shugar and of Tomas, and their distinct differences in power, was made possible by the powerful and mysterious sorcerer Macros the Black.
