Crest
Diasomnia's crest depicts the Fairy of Thorns' dragon form. At the bottom, there is a small teaser of her infamous spinning wheel, and an image of her horns protrude from the top of the crest.

Trivia

 * It was built around the idea of the Fairy of Thorns's castle, and the weather follows: sunlight is scarce in Diasomnia. In Sleeping Beauty, Maleficent's castle is depicted surrounded by dark clouds.
 * Diasomnia students tend to have excellent magical capabilities overall.
 * The word "Diasomnia" comes from the Latin "dia", meaning "going through, across", and "somnia", meaning "dreams."
