Sud

"earth"

- My Earthbending master, Sud, was uncompromising, stubborn, and blunt... and a life-long friend.

Sud was Avatar Roku's Earthbender teacher, who taught him Earthbending when he was learning the four elements.

History
Not much is known about Sud except that he was a citizen of the Earth Kingdom when Roku was a young man. He was likely also a skilled and powerful Earthbending Master, being given the honor of teaching the Avatar the element. He trained Roku in the art of Earthbending, the last element Roku needed to master to become a fully-realized Avatar. Once mastered under Sud's tutelage, Roku beat his teacher in a race up a mountain by surfing on rocks. By the time Sud reached to top of the hill, Roku was already sitting there brewing a pot of tea. Sud laughed, and they sat down to enjoy the hot beverage. They remained very good friends afterward, and having mastered all four elements, Roku began his time as the Avatar.
