Raffard the White was a legendary sorcerer and alchemist who lived before the creation of the Brotherhood of Sorcerers. His history indicates that he made noble and beautiful things. However, those who delve a little deeper found out that he also secretly ruled Temeria. Raffard was vehemently against the formation of the Brotherhood, which would ultimately result in his demise. In the battle between the two forces, Raffard died along with his knowledge of the arcane arts.
There is a possibility that Raffard the White was loosely inspired by Saruman the White from The Lord of the Rings. Both carry a similar name and are powerful mages.
