Razdal mo Eraz, known as Grazdan mo Eraz in the books, is a character that hails from A Song of Ice and Fire and Game of Thrones. His name is changed to avoid confusion with other characters named "Grazdan", since the name is extremely common in his region. He is a wealthy slave trader from Yunkai, and a member of the Wise Masters.
He was portrayed by George Georgiou in the television series.

Grey Worm then offers one of the masters to be executed as a punishment. Razdal and Belicho pick Yezzan for being lowborn.
