San

San was an Earth Kingdom native from Ba Sing Se and the father of Mako and Bolin.

Leaving Ba Sing Se
A man with big dreams, San wanted to escape poverty by leaving his family's abode in the Lower Ring and moved to Republic City, much to the dismay of his father, with whom he argued heatedly before departing. Sometime after he moved to Republic City, San met his eventual wife, a woman of Fire Nation descent, and they had two children, Mako and Bolin.

Death
In 160 AG, San and his wife were killed by a firebending mugger, leaving their children orphaned. San's family in Ba Sing Se did not receive the news of his and his wife's death until eleven years later, when the sad truth was revealed by Mako and Bolin during a visit with the family.

Legacy
Mako used to wear San's scarf growing up. However, upon meeting his grandmother, Yin, Mako decided to give the memento to her.
