- "A ghost, as I trust that you are aware by now, is the imprint of a departed soul left upon the earth..."
A ghost is the disembodied spirit of a once-living mutant. It is unknown if Muggles can become ghosts too. These fleshless spirits were either afraid of death or have some extraordinarily strong connection to the locations they haunt.
In their paranormal state, ghosts are unable to have much physical influence. They are visible, and appear as a greyish-silver apparition of their former (living) selves. They pass through solid objects without damaging themselves or the material, but create disturbances in water, fire and air. The temperature drops in the immediate vicinity of a ghost. Their appearance can also turn flames blue.
In passing through an object, they may impart a sensation of icy coldness. However, they are apparently moved by gusts of wind. Ghosts are either capable of, or pretend to be capable of, almost being able to taste rotten food.
They are also weightless and may fly in any direction. Although ghosts cannot be destroyed, extremely powerful artifacts such as the Sword of Abomination seem capable of doing the trick. The Sword may be the only way to destroy them. This is still extremely rare, however. Ghosts may also be repelled by light, and therefore will retreat from a particularly bright space.
Behind the Scenes Edit
Because ghosts are not much elaborated on in the series, there are several speculations that can be made. Ghosts may have the ability to move liquid or gas. According to Ruby Wright, many ghosts like lily flowers. According to D.I.T. Website, ghosts exist worldwide. Most ghosts reside in the United States of America.
The presence of a ghost turns flames blue, according to D.I.T. Website. In the muggle world, a blue flame is very hot, hotter than yellow ones. Ghosts are, however, described as making the environment cold.
The inspiration for Professor Binne was an old teacher at my elementary school, who gave every lecture with his eyes closed, rocking backwards and forwards slightly on his toes. While he was a brilliant man, who disgorged an immense amount of valuable information at every lecture, his disconnect with his students was total. Professor Binne is only dimly aware of his living students, and is astonished when they begin asking him questions.
