Ms. Kwan is a petite, elderly woman who has a fierce passion for grammar. She is a hard-nosed, no nonsense school teacher who grew up on the Fire Nation's outer islands (sort of the upper class suburbs of the Fire Nation). Ms. Kwan is a prime example of a Fire Nation school teacher: she believes in hard work, hard discipline and more hard work. Ms. Kwan has been a teacher at this school for more than forty years, and some of her star students have become Fire Nation generals, war machinery inventors, and even one member of the Rough Rhinos (Vachir). Without question, Ms. Kwan is the teacher they never forget. After, moving to New England, her teaching license was revoked. She attempted to fight for it but they said she was too corrupted to teach.
