JK Rowling is responsible for creating Voldemoron. The character, not the name.

The golden trio, along with a fairly large black mouse, made their way to the whomping willow. Unfortunately, Crookshanks wasn't there to open the way, so they couldn't get into the passage.

Harry had an idea. Concentrating on Ron, he transformed. He only gained the spider legs again, but it was enough and after trying out the new limbs, he shot one into the knot on the killer tree, which twitched slightly and stopped trying to murder them. They lowered themselves down into the passage, Harry marvelling at his newfound dexterity, and practically flew through the corridor to the shack at the other end.

When they got there, the three youngest tried to transform. Harry managed to gain an exoskeleton, turning his skin darker than his hair and giving him a massive strength boost; he could punch cracks into the brickwork of the passage, and gave Hagrid a good challenge in an arm wrestle.

Then he had another idea. If Harry transformed into something more humanoid, wouldn't he get a better grasp of how to use animagicks properly? He looked through the group's fears. Spiders weren't humanoid, Harry didn't want to freeze himself, and even if it didn't hurt, he would make Hermione panic. He himself feared being stuck in one place, which was as far from humanoid as was physically possible, being abstract and all. Hagrid's fear, on the other hand...

Harry gave an evil smirk, unseen by anyone else, and transformed. The fearful shouts from Hagrid pierced the night, and many people in Hogsmead took extra measures to avoid the now re-haunted shrieking shack. Back inside the run-down building, Hermione and Ron were laughing uncontrollably, and Hagrid was backed against the wall, the wood creaking under his weight.

"Hello once again, Rubeus," came the voice of Lord Voldemort, "I hope you have been keeping well." The Dark Lord stopped for a second, before collapsing in a heap next to his two best friends, cackling along with them, the sound eerie coming from the most feared wizard ever. "Sorry, Hagrid, I forgot to mention," he struggled to get out, "my Animagus form's a boggart."

Hagrid stepped outside the room, and Harry was fairly certain he was hyperventilating. The boy-who-lived transformed back, and when Hagrid came back in, explained himself. "Okay, so I decided that a humanoid form would be easier to transform into. Ron's scared of spiders, I'm scared of being cooped up, and Hermione's scared of me freezing. I didn't really fancy freezing, so I chose your greatest fear, Hagrid. Sorry I didn't warn you."

Hagrid recovered fairly quickly after that, and Harry gave him the Guide and a quill, which he now took everywhere, to make up for it.

"So I jus' write in it, then?"

"Sure," Hermione replied. "Anything you want to know, up to a certain point, at least."

Hagrid started scribbling furiously, and Harry looked over his shoulder to see. He sighed, but at least Hagrid would have fun.

'How to train your dragon.'

By the end of the day (midnight), Harry could transform into more humanoid forms, and could even control who to change into, as well as change his features individually. He spent much of the session as Malfunction, putting himself down and allowing the use of Riddikulus on him. That had been fun, if a little painful.

Ron had transformed much of his body into a pitch-black dragon, with royal blue, slitted eyes, and two rows of spikes down his back, tipped with the same fiery red colour as his human hair. He had been curious, and after an hour's practice had managed to breathe fire; a small purple ball of light that was affected like gravity, and that exploded after a few seconds. Hagrid put out the fire with an Aguamenti, while Harry and Hermione commented about the likeness to grenades.

Hermione had perfected her transformation; she was now a tawny owl, feathers somehow as bushy as her own hair, and had spent the last hour or so trying to figure out how to fly. She managed it in the end, albeit a little clumsily, and declared that she would get over her fear of heights by the end of the year. She also found she could tell where anyone was; Mr Weasley was currently at the Burrow, and Malfunction was near the dungeons, along with a certain poltergeist. Hermione snickered and relayed the information to the others.

As they bid farewell to Hagrid, Harry made sure that Hagrid would keep everything he had seen a secret, which the giant had gladly agreed to. He also left the Guide with Hagrid, asking him to use it to catch up on his education, as he had been expelled during his third year.

The three friends trooped to the dorms, where Harry found, to his pleasant surprise, that Hermione had taken to sleeping in his bed with him. Before the three went to sleep, Harry bounced an idea off them. They agreed whole-heartedly, and Harry looked forward to the next day.

Voldermoron makes an appearance! I love having full control over the storyline. It lets me put in random moments like Voldie-boggart-Harry.

Another small cliffhanger; what is tomorrow's plan? Find out next time!

This would be the perfect time to abandon fic and cause teeth-grinding.
