Sir Sternivus Swinedimple founded Swinedimples Academy in Dragon Quest IX: Sentinels of the Starry Skies and was its first headmaster. He is mentioned to have been a very harsh and bitter man who loved to punish students for even minor misdeeds.
Many years after his death his ghost haunted Swinedimples academy when a fygg was placed on his gravestone. When the hero confronts him during the story, he turns into the Dreadmaster and attacks. After his defeat, he decides that the discipline in Swinedimples Academy was up to a decent standard after all, and returns to his eternal rest, releasing the fygg to the hero.
Sternivus Swinedimple is very similar to Severus Snape from the Harry Potter series.
