Bumi's advisor was the consul of the eccentric KingBumi. His role was to advise the king on important matters and enforce Omashu's rules and traditions on the citizens. He served as the Grand Secretariat of Omashu, like Long Feng was the Grand Secretariat of Ba Sing Se.
Unlike Long Feng, he did not exercise much control over King Bumi or Omashu's affairs other than enforcing rules. He was given the nickname 'Goody Two-Shoes Consul' by Bumi. Although he was Bumi's advisor, this man was an ally of Lian, the machine maker.
The consul worked against the king and tried to prevent Team Avatar from leaving Omashu, but fainted after this fateful encounter.[1]
