They infest the darkest, filthiest places, they glory in decay and despair, they drain peace, hope and happiness out of the air around them. Even Muggles feel their presence, though they can't see them. Get too near a Dementor and every good feeling, every happy memory, will be sucked out of you.
Even Muggles Can Sense Their Presence
Of course, a human can be attacked by a Dementor too (as we see with Dudley Dursley), but the mere presence of a Dementor near any living person, whether they're witch, wizard, or Muggle, will have a negative effect on them.
Yes, they can.
It's mentioned that they CAN see giants, dragons, etc. Non-human creatures such as house elves and goblins have their own ways of going unseen, or of blending in. Structures like Diagon Alley and Platform 9 3/4 are hidden by magic." Adieu!
And the only reason the Dementors choose to follow Voldemort is because he frees them from their duty to Azkaban, allowing them access to the richer pickings on the mainland.
Albus Dumbledore harbors an intense dislike of dementors, noting he has long felt the Ministry of Magic erred in "allying" with such creatures, implying that dementor society in general exists apart from the general wizarding world.
Because dementors seek to suck out the souls of their prisoners, it's plausible that they are especially drawn to Harry because — as it is revealed in the last book — he actually possesses a fragment of Lord Voldemort's soul as well.
The Weasleys
' We finish on a family who are technically quite pure-blood, but are deemed 'blood traitors' by various peers, and seem proud of it. It is, indeed, the Weasleys' compassion and morals that led to several members marrying half-bloods, Muggle-borns, etc.
The pure-blood wizards and witches featured in the Harry Potter books are almost all supremacists, while there are some of them who do not advocate ancestral superiority; the Potters, Weasleys, and Longbottoms are old pure-blood families, but no known members of these families are sympathetic to supremacist aims.
Diagon Alley is a high street located in London. It is accessible to the wizarding world, to which it is something of an economic hub, but hidden from Muggles (non-magical people). However, Muggles are allowed access to it if they need to accompany their Muggle-born magical children.
"The reason Harry blacked out during dementor attacks is because this act of selfless love by Lily causes Voldemort unendurable pain whenever he experiences it. Like when he tried to possess Harry or touch him via Quirrel. Harry blacks out because one part of his soul is in agony while the other is not.
Harry's godfather Sirius Black endured 12 years in solitary confinement in Azkaban for a crime he did not commit. By focusing on his innocence he was able to survive and escape the merciless Dementors, and would later narrowly avoid the Dementors' Kiss with help from his godson.
Yes, although we haven't met any in the seven Harry Potter novels. The Pottermore introduction to Slytherin says: […] we have traditionally tended to take students who come from long lines of witches and wizards, but nowadays you'll find plenty of people in Slytherin house who have at least one Muggle parent.
Reproduction. Dementors breed by surrounding themselves with large amounts of a special fog which they exude. New individuals, already fully formed, will gradually congregate from the mist. Dementors usually breed in large groups.
Ekrizdis is a minor yet pivotal antagonist in the Harry Potter universe. He was an immensely evil wizard who lived in the 15th century in medieval Britain, it is believed he was either the creator of the Dementors or that his insane experiments and torture caused the Dementors to first manifest.
In Prisoner of Azkaban, Harry's reaction to the Dementors is a direct representation of the experience of depression. Dementors are guards for the prison, Azkaban, and come to guard Hogwarts when there is a risk of an escaped prisoner.
He's a pure-blood wizard, proud Slytherin and Harry Potter's arch rival at Hogwarts. Happy birthday, Draco Malfoy!
Luna Lovegood is a Pureblood witch, who was sorted into Gryffindor House during Harry Potter's second year at Hogwarts School of Witchcraft & Wizardry.
Having rendered unknown, shady, (and almost certainly magical) services to King William I, Malfoy was given a prime piece of land in Wiltshire, seized from local landowners, upon which his descendants have lived for ten consecutive centuries.
Harry James Potter holds half-blood status in Rowling's imagined wizarding world because his mother is Muggle-born and his father is pure-blood. There are three main blood statuses; pure-blood, half-blood, and Muggle-born, which are all methods of determining a witch or wizard's magical lineage.
One of the wealthiest Wizarding families in Britain, the Malfoys were known for their connections to other pureblood families and their covert influence over the magical government. In contrast to the Weasleys, the Malfoys were traditionally sorted into Slytherin and supported pureblood supremacy.
Blood purity
Muggle-born Slytherins existed, but were very rare, as noted insultingly by Scabior the Snatcher. There had also been definite examples of half-bloods sorted into the house, including Tom Riddle, Dolores Umbridge, and Severus Snape.
Harry describes Umbridge to Sirius Black, saying that she's vile enough to be a Death Eater, despite not being one. Umbridge is also depicted to be a prejudiced person, despising half-breeds and Muggle-born witches and wizards to the point of firing Hagrid due to his half-giant birth status.
Chocolate is the perfect antidote for anyone who has been overcome in the presence of Dementors, which suck hope and happiness out of their surroundings.
By his own admission, Lupin believed Sirius was guilty of dooming Harry's parents and committing the mass-murder he was imprisoned for. He believed this throughout Prisoner of Azkaban, only understanding he was innocent when he saw Peter Pettigrew on the Marauder's Map.
