'Can you tell us about Dementors?'

Remus wasn't surprised by that question, of course the students would ask. Their school was surrounded by the things, they had all met the abominations on the Hogwarts Express. It was a fair question and so Remus had already prepared to explain about Dementors for this lesson. 'First let's start off with what do all of you know about Dementors?' he asked the class.

'They are evil,' Ron Weasley muttered.

'They cause Scar heads to pass out like babies,' Draco Malfoy said, sending a smirk to Harry Potter.

'I heard they..they can't be killed,' Neville Longbottom announced weakly.

'I read that they feed on happiness,' that was Hermione Granger.

'If they kiss you they destroy your soul,' Faye Dunbar added.

Remus let the students continue on, but that was the majority of their points. After they had all finished Remus decided to correct them. 'Only Neville was actually correct,' he announced ignoring the look of anger from Hermione and the look of surprise from Neville.

'But Professor!It's quite well known that Dementors feed on happiness,' Hermione announced, hand in the air but too impatient to wait to be called on.

Remus nodded, 'yes Miss Granger that is the commonly accepted belief but it is a false belief. Tell me what is the primary weapon used against Dementors?'

'The Patronus Charm,' she announced straight away. 'It is a Newt Level charm that creates a corporeal form made from happiness and magic. It is primarily used to fight off Dementors but it can also be used to send messages and is said to be able to help people cope with depression.'

'But don't Dementors eat happiness?' Blaise Zabini asked, confusion clear on his face. 'Why would what they eat fight them off?'

All of the other students voiced this query as well, no one seeming to have the answer to this. Well no one except Remus himself. 'What Dementors do is they don't feed on happiness, in fact Dementors do not eat at all, they destroy happiness as they were created to do.'

'Why does a Patronus work then?'

'Who the bloody hell would create Dementors?'

'Mr Weasley that will be five points from Gryffindor for language,' Remus stated. 'As for why the Patronus works, the Dementors hate happiness and joy and similar emotions, it is why they seek to destroy it. A strong enough Patronus however is too much for them to destroy and so it causes them to flee.'

'But why would someone create Dementors?' Harry asked, an angry look on his face.

Remus grinned, this was the question he always loved to explain. It had such a beautiful answer that seeing everyone react to it never failed to amuse him. 'You see once upon a time there was a dark wizard, a vile wizard who lived on the outskirts of a small town and this town was said to be the happiest place on Earth. All of it's residents were so happy and joyful, bright and bubbly and this wizard hated it. He hated that all of these people were happy and he was not. He tried everything and anything he could to make the townspeople not happy, trick after trick, curse after curse, scheme after scheme and nothing worked, nothing could dampen the towns spirits.'

The class were all at the edges of their seats right now, intent on hearing what would happen next. So Remus stopped to conjure some tea, letting them wait just that little bit longer. 'The dark wizard eventually tried to create dark doppelgangers of the towns residents. They were to spread misery and depression wherever they go, where the town spread light and warmth and cheer, these beings were to spread darkness, cold and depression. Of course like every other plot of the dark wizard it did nothing to dampen the spirits of the town, but he had still managed to create Dementors as we know them today.'

'Who created Dementors?' Harry asked, quietly. Hatred for the unknown wizard marred his face. Remus couldn't blame him, Dementors were horrible for the average person, they were pure torture for someone like Harry. Still Remus was going to have his fun and stretch this out just a bit longer.

'Why don't you tell me? Who here knows who this wizard was?' he asked the class. Honestly their guesses weren't bad, Voldemort, Grindelwald, Hugo the Foul, Salazar Slytherin, Imhotep. They had many good guesses, all were wrong however.

'Just tell us already,' Draco Malfoy demanded, getting impatient.

'I'll give you hints, surely someone here can figure it out,' Remus grinned. 'But let's see facts about this dark wizard well the first thing you need to know is he was a mean one, a heel, he was said to be as cuddly as a cactus, it was rumoured that he had termites in his smile and that no one would touch him with a thirty nine and a half foot pole,' Remus could see the recognition in some of the students eyes, they knew who the dark wizard was but they just couldn't believe it. 'It wasn't known why he was so grumpy, people believe that maybe his shoes were too tight, I however believe that his heart was two sizes too small.'

The class was silent, no one moved. No one said anything. Remus wasn't even sure if they were breathing.

'The GRINCH!' Harry shouted. 'You're saying The Grinch is real and he created Dementors!?' The other Muggleborns in the class were just as shocked, the Wizardborn were not reacting much better. This was everything Remus hoped it would be and then some. It never failed to break peoples minds to find out that The Grinch was not only real at one point but created some of the most dangerous beings in the world. Still Remus wasn't sure why people were surprised for a man who could steal Christmas anything was possible, and nothing was too petty.

So yes this is just an idea I had that I wanted to eventually fit into a Harry Potter fic but I never have the patience to get to Third Year. Be honest at what point did you realize who I was alluding to?
