I'm unable to figure out when was the first Dementor created and by whom. I know they don't breed and grow out of despair and gloom and they can't be destroyed. They have been guarding Prison of Azkaban since long time but where did they come from or who created them for the first time?

When reading the , I took away the following highlights (emphasis mine):  TL;DR - Did Ekrizdis create Dementors?      The fortress upon it was originally home to a little-known sorcerer   who called himself Ekrizdis. Evidently extremely powerful, but of   unknown nationality, Ekrizdis, who is believed to have been insane,   was a practitioner of the worst kinds of Dark Arts.     Those who entered to investigate refused afterwards to talk of what   they had found inside, but the least frightening part of it was that   the place was infested with Dementors.     Others were afraid of what might happen to the Dementors infesting the   building if they deprived them of their home. The creatures were   already strong and impossible to kill; many feared a horrible revenge   if they took away a habitat where they appeared to thrive. The very   walls of the building seemed steeped in misery and pain, and the   Dementors were determined to cling to it.     The fortress was therefore left abandoned for many years, a home to   continually breeding Dementors.     Experts explained to him that the only reason the Dementors were   (mostly) confined to the island was that they were being provided with   a constant supply of souls on which to feed. If deprived of prisoners,   they were likely to abandon the prison and head for the mainland.    My feeling is that it is possible that Ekrizdis created the Dementors. However, the way the text uses tense and wording it could go either way. It seems that if they were not created on the island that the vast majority of them were hanging around there. Is there any other evidence to confirm the Dementors were created by Ekrizdis rather than just "existing" and being drawn to the island?  Related, but does not touch on initial creation and possible link to Ekrizdis:   It would not be the first time a dark creature were created;  created the first Basilisk. Although, a Basilisk is a physical creature, while a Dementor is more of spirit/embodiment.

In Prisoner of Azkaban we learn that Sirius Black escapes from Azkaban. At some point we learn that      Scabbers is actually Peter Pettigrew (Wormtail). "Scabbers" fakes his own death and escapes from Ron. He did this because he realized that Sirius Black was coming after him.  He was one of the Marauders so he knew of the secret passages out of Hogwarts so probably could have left without needing to go past a Dementor.  There was quite a bit of time between him faking his own death and the moment he does leave Hogwarts after escaping from Sirius. During that time he knew Sirius was nearby and yet stayed at Hogwarts.   With that said why did Scabbers stay within Hogwarts' grounds instead of leaving to find a new home elsewhere?

Is Morgoth, the original enemy in J. R. R. Tolkien's Middle-earth ever visually described? I envisage him as a bigger, meaner version of the physical Sauron, but I cannot find any reference in The Simarillion.

From what I’ve read on here, people remained at Hogwarts after Dumbledore’s death, mainly in Dumbledore’s Army. But why wouldn’t the parents just have their children come home?  Also, I know the Ministry was largely controlled by Death Eaters, but how did Snape remain Headmaster, especially with someone like McGonagall still present?

Who built the fortress of Dol Goldur, and when was it built? And was it always a place for evil, or Sauron just occupied it?  Despite the fact that Mordor is much better fortified; artificially by the old fortifications,  and geographically, as it is surrounded by the mountains. Also considering the presence of mount doom that seem to enhance Sauron's power, Sauron chose to start his campaign from Dol Goldur, despite Mordor being ready for quite some time.  Why did he choose this enigmatic fortress, and not go straight for Mordor or even go earlier?

Rereading the Prisoner of Azkaban, this interesting question(at least to me) popped in my head. What shape would a boggart take if a person is never depressed about anything, has no evil memories whatsoever for the boggart to feed on or has no fear?

Why did Voldemort never seek the Hallows before the events of the second wizard war?  It seems it would have been much easier for him to retrieve them.  James had the cloak, Regulus had the resurrection stone(not sure if I remember that correctly, I could be wrong), and Dumbledore had the elder wand.  It seems that it would have been much easier for Voldemort to get to the three seeing as the cloak was with Harry who's location was unknown and the stone was within the snitch Harry caught, which only he could open.  So, why did Voldemort wait to seek the Hallows?

In Harry Potter and the Prisoner of Azkaban, while Harry is eavesdropping on the group of adults discussing Sirius Black in The Three Broomsticks, Madam Rosmerta objects to the Minister for Magic about the presence of Dementors, but Fudge demurs.      ‘You know that the Dementors have searched my pub twice?’ said Madam Rosmerta, a slight edge to her voice. ‘Scared all my customers away ... it’s very bad for business, Minister.’   ‘Rosmerta, m’dear, I don’t like them any more than you do,’ said Fudge uncomfortably. ‘Necessary precaution ... unfortunate, but there you are ... I’ve just met some of them. They’re in a fury against Dumbledore – he won’t let them inside the castle grounds.’   Prisoner of Azkaban - page 151 - Bloomsbury - chapter 10, The Marauders Map   We know that Dementors can take orders. Dolores Umbridge sent two Dementors to attack Harry at the beginning of Harry Potter and the Order of the Phoenix, so they must possess some kind of communication abilities.   Can Dementors talk? Do wizards communicate with Dementors via Legilimency? How did Fudge find out that the Dementors were in a fury specifically because Dumbledore wouldn't let them into Hogwarts castle?  &#9733; I'm looking for a canon answer (the Harry Potter novels, the three supplemental books, JKR interviews, or Pottermore) and do not prefer an answer from the HP Wikia or the Wikipedia. I'll definitely consider any answer composed in the spirit of canon.

The only prison that I can remember being mentioned in Harry Potter is Azkaban.  Some simple research indicates one person was imprisoned for owning Sphinxes and Hagrid was sent there, apparently as a precautionary measure, after the re-opening of the Chamber of Secrets.  This implies that even though living in Azkaban is a terrible ordeal, that it's possible to be sent there for smaller crimes.  Are there other prisons in the magical world, or is Azkaban the only one?  And if there are, has JKR ever made any comments about why one would be sent to Azkaban as opposed to another prison?  Are there also prisons that might be more like a "minimum security" setup without dementors for lesser crimes?

I was playing LOTR War in the North the other day. Despite its inaccuracy, there was one part where I had to fight a stone giant. I don't recall this from any of the books I've read, which are numerous. So I would like to know.   Where did giants come from? Are they Maia spirits like those of the Eagles and Ents? Do they originate from Melkor (Morgoth)?

So I just finished watching  but I could not understand if the murders took place or not?  From watching the movie I was certain the murders indeed happened and that's why the case was going on.  But if it did happen then why did Dr. Mallick say that Malcolm the convicted was thinking the accidents in his head? Had the murders already happened, and was Malcolm responsible? Why has he not been punished?   Perhaps I could not understand the plot clearly. I am also not sure if Timothy became Malcolm after he became older because the murders happened 4 years ago!

I checked the Wikipedia article and some interviews, and haven't found any specific answer.  What specifically does the "awakening" of the Force in the title refer to?  Was the Force somehow asleep or dormant? (which would, since it Binds The Galaxy Together, explain the Inflationary cosmological models).  Or that there were no active Force users since Vader and Sidious offed every Jedi and then each other? We know Luke's still around.  Or something else?  Canon or word-of-god answers only, please.

There have been    recently regarding Patronuses, and who could summon one, and why. The general consensus seems to be that Death Eaters could not summon Patronuses, since they are Very Bad People.  My question is, if Death Eaters supposedly were unable to summon a Patronus under any circumstances, then why could Dolores Umbridge summon one? Umbridge was sick and twisted, at least to the level of most Death Eaters, yet we see in Deathly Hallows that Umbridge had her Patronus, a cat, guarding her from Dementors while she was persecuting Muggleborns.

Based upon , J.K. Rowlings has apparently stated "You cannot destroy Dementors, though you can limit their numbers if you eradicate the conditions in which they multiply, ie, despair and degradation."  Does this mean that the number of Dementors is always either increasing or remaining the same?  If they cannot be destroyed, does that mean they are immortal?  Or do they die of "natural causes"?

I think the first time we see an animal or supposedly living being created by a spell in Harry Potter is when Harry and his friends are in the Transfigurations class and Professor McGonagall turns her desk into a pig and back into a desk.  There's also a reference, in the same scene, that Harry realizes it'll be a while before the students are changing furniture into animals.  I don't remember reading anything in the books (but a few of mine have been loaned out and haven't come back for months and months!), but wondered if there was anything elsewhere, from JKR or other somewhat authoritative sources about whether animals created by transfigurations or by other spells are actually alive.  Are they full biologically complete versions of the animals?  If so, do they have the same sense of awareness of an authentic version of the same animal?  I can't remember whether or not I read somewhere that spells can't create life.  If that is the case, then what drives the behavior in an animal created by a spell?

Sirius Black and a few Death Eaters escape Azkaban and seem to operate after that with their wands intact.  How come?  If a mere expulsion from Hogwarts entails wand destruction (as happened with Hagrid), shouldn't an Azkaban sentence entail the same?  And even if we imagine that the perceived impossibility of escape from Azkaban made it seem unnecessary to destroy the wand, this would apply to Sirius but not to Death Eaters.  PS: Two comments suggested that the escapees acquired new wands. It would be nice to have a more definitive answer than just a suggestion or a list of possibilities. Thanks.  PPS: Returning the personal property to a released prisoner is one thing, but the wand is a different matter: this is usually the tool of the crime, and I don't see how it can be argued that it should be returned and not destroyed. Again, Hagrid had his wand destroyed and he was not even sentenced to Azkaban.  PPPS: Maybe wand destruction is only done for non-fully-qualified wizards?

How did Barty Crouch Jr. and the other Death Eaters not get caught by the Ministry, when they have tattoos on their arms of the Dark Mark? Is the use of a cloak alone enough, no raids on their body parts? Even Barty Crouch Jr's father was shocked when he was revealed to be a Death Eater.
