The flag of Tretrid, also known as King Ælfric's Flag (Tretridian: ᚫᛚᚠᚱᛁᚳᛋᚠᚪᚾᚪ, Ælfricsfana) is a blue-and-green flag with a white cross that extends to the edges of the flags.
Historical accounts of the flag's usage by the Kings of Tretrid date all the way back to the late 13th century, though it is believed the usage of the standard began earlier. The flag is traditionally attributed to Ælfric I, the King of Norþrenia, during his campaigns that would eventually unify Tretrid. The flag is one of the oldest flags to still be in use.
An origin legend for the flag states that Ælfric started using the flag after being shown the flag in a vision from the gods and being promised never-ending victory if he flew it in battle.
