The Polyjuice Potion
The Polyjuice Potion, which is a complex and time-consuming concoction, is best left to highly skilled witches and wizards. It enables the consumer to assume the physical appearance of another person, as long as they have first procured part of that individual's body to add to the brew (this may be anything - toenail clippings, dandruff or worse - but it is most usual to use hair). The idea that a witch or wizard might make evil use of parts of the body is an ancient one, and exists in the folklore and superstitions of many cultures.
The effect of the potion is only temporary, and depending on how well it has been brewed, may last anything from between ten minutes and twelve hours. You can change age, sex and race by taking the Polyjuice Potion, but not species.
The effect of the potion is only temporary, and depending on how well it has been brewed, may last anything from between ten minutes and twelve hours. and last however long the author needs it to last.
I remember creating the full list of ingredients for the Polyjuice Potion. Each one was carefully selected. Lacewing flies (the first part of the name suggested an intertwining or binding together of two identities); leeches (to suck the essence out of one and into the other); horn of a Bicorn (the idea of duality); knotgrass (another hint of being tied to another person); fluxweed (the mutability of the body as it changed into another) and Boomslang skin (a shedded outer body and a new inner).
The fact that Hermione is able to make a competent Polyjuice Potion at the age of twelve is testimony to her outstanding magical ability, because it is a potion that many adult witches and wizards fear to attempt.
Shame she stopped carefully selecting things after first few books.
Why do you need "outstanding magical ability" to make a potion?
Ability to read and follow instructions, sure.
I can understand that. But "outstanding magical ability"?
Do they need to cast magic in the potion somehow?
In the world of Harry Potter, a ghost is the transparent, three-dimensional imprint of a deceased witch or wizard, which continues to exist in the mortal world. Muggles cannot come back as ghosts, and the wisest witches and wizards choose not to. It is those with 'unfinished business', whether in the form of fear, guilt, regrets or overt attachment to the material world who refuse to move on to the next dimension.
Having chosen a feeble simulacrum of mortal life, ghosts are limited in what they can experience. No physical pleasure remains to them, and their knowledge and outlook remains at the level it had attained during life, so that old resentments (for instance, at having an incompletely severed neck) continue to rankle after several centuries. For this reason, ghosts tend to be poor company, on the whole. They are especially disappointing on the one subject that fascinates most people: ghosts cannot return a very sensible answer on what it is like to die, because they have chosen an impoverished version of life instead.
Ghosts can pass through solid objects without causing damage to themselves or the material, but create disturbances in water, fire and air. The temperature drops in the immediate vicinity of a ghost, an effect intensified if many congregate in the same place. Their appearance can also turn flames blue. Should part or all of a ghost pass through a living creature, the latter will experience a freezing sensation as though they have been plunged into ice-cold water.
Witches and wizards are much more susceptible to what Muggles call paranormal activity, and will see (and hear) ghosts plainly where a Muggle might only feel that a haunted place is cold or 'creepy'. Muggles who insist that they see ghosts in perfect focus are either a) lying or b) wizards showing off - and in flagrant breach of the International Statute of Secrecy.
Poor Muggles.
They can't even be ghosts. Only wizards are so "cool".
And all those people who think they have seen ghosts?
Yeah, they are dirty liars or, like always, a wizard did it.
Chamber of Secrets
The subterranean Chamber of Secrets was created by Salazar Slytherin without the knowledge of his three fellow founders of Hogwarts. The Chamber was, for many centuries, believed to be a myth; however, the fact that rumours of its existence persisted for so long reveals that Slytherin spoke of its creation and that others believed him, or else had been permitted, by him, to enter.
There is no doubt that each of the four founders sought to stamp their own mark upon the school of witchcraft and wizardry that they intended would be the finest in the world. It was agreed that each would construct their own houses, for example, choosing the location of common rooms and dormitories. However, only Slytherin went further, and built what was in effect a personal, secret headquarters within the school, accessible only by himself or by those he allowed to enter.
Perhaps, when he first constructed the Chamber, Slytherin wanted no more than a place in which to instruct his students in spells of which the other three founders may have disapproved (disagreements sprung up early around the teaching of the Dark Arts). However, it is clear by the very decoration of the Chamber that by the time Slytherin finished it he had developed grandiose ideas of his own importance to the school. No other founder left behind them a gigantic statue of themselves or draped the school in emblems of their own personal powers (the snakes carved around the Chamber of Secrets being a reference to Slytherin’s powers as a Parselmouth).
What is certain is that by the time Slytherin was forced out of the school by the other three founders, he had decided that henceforth, the Chamber he had built would be the lair of a monster that he alone - or his descendants - would be able to control: a Basilisk. Moreover, only a Parselmouth would be able to enter the Chamber. This, he knew, would keep out all three founders and every other member of staff.
"a personal, secret headquarters within the school, accessible only by himself or by those he allowed to enter." and "he had developed grandiose ideas of his own importance to the school. No other founder left behind them a gigantic statue of themselves or draped the school in emblems of their own personal powers" sounds a lot like Dumbledore to me.
Btw, If Slytherin have been "always evil" why did the others made Hogwarts with him?
Weren't they all "the best of friend" on the beginning?
The sword of Gryffindor was made a thousand years ago by goblins, the magical world's most skilled metalworkers, and is therefore enchanted. Fashioned from pure silver, it is inset with rubies, the stone that represents Gryffindor in the hour-glasses that count the house points at Hogwarts. Godric Gryffindor's name is engraved just beneath the hilt.
The sword was made to Godric Gryffindor's specifications by Ragnuk the First, finest of the goblin silversmiths, and therefore King (in goblin culture, the ruler does not work less than the others, but more skillfully). When it was finished, Ragnuk coveted it so much that he pretended that Gryffindor had stolen it from him, and sent minions to steal it back. Gryffindor defended himself with his wand, but did not kill his attackers. Instead he sent them back to their king bewitched, to deliver the threat that if he ever tried to steal from Gryffindor again, Gryffindor would unsheathe the sword against them all.
The goblin king took the threat seriously and left Gryffindor in possession of his rightful property, but remained resentful until he died. This was the foundation for the false legend of Gryffindor's theft that persists, in some sections of the goblin community, to this day.
The question of why a wizard would need a sword, though often asked, is easily answered. In the days before the International Statute of Secrecy, when wizards mingled freely with Muggles, they would use swords to defend themselves just as often as wands. Indeed, it was considered unsporting to use a wand against a Muggle sword (which is not to say it was never done). Many gifted wizards were also accomplished duellists in the conventional sense, Gryffindor among them.
There have been many enchanted swords in folklore. The Sword of Nuadu, part of the four legendary treasures of Tuatha Dé Danann, was invincible when drawn. Gryffindor's sword owes something to the legend of Excalibur, the sword of King Arthur, which in some legends must be drawn from a stone by the rightful king. The idea of fitness to carry the sword is echoed in the sword of Gryffindor's return to worthy members of its true owner's house.
Well, of course the goblin King (shame it wasn't Jareth. I wonder how would Gryffindor deal with him) was the untrustworthy, greedy, deal breaking one.
It's not like any true Gryffindor would ever try to get back on a deal, right?
Oh, wait . . .
This just sounds so forced to me.
Gryffindor not killing the goblins, the reason wizards had swords just all of it.
And thanks JKR.
If you hadn't told us that "The sword of Gryffindor" is HP version of Excalibur we would have never seen the similarities.
