While you are at Hogwarts, your triumphs will earn your house points while any rule-breaking will lose house points.
~ Minerva McGonagall addressing her students.

Heroic Disciplinarians are heroes and heroines (usually parents, relatives, or teachers) who discipline other people to get them to learn right from wrong. Some are very strict (sometimes too much so, as in King Triton's case), but they're generally kind to those they care about. Examples include Professor McGonagall, Queen Elinor, and Mufasa.
