A magical journey that begins in Azkaban

"My little pony, you don't need to judge the affairs of our tribe." Bain stood in front of Rogge, his huge body bringing a strong sense of oppression.

"Okay, Baine. Maybe Firenze has good intentions." Ronan looked up at the night sky and said in a sad tone.

"My little pony, my name is Ronan, and the Mars is particularly bright tonight." Ronan muttered, not sure what prophecy he understood from the celestial phenomena.

"Roger Travis, nice to meet you." Rogge saw Ronan who was obsessed with Mars, and he had an idea and took out the star map he had printed.

"Ronan, I have a star map from about 700 years ago. Can you help me look at it?" He opened the star map with his wand, and the stars on it shone with magical light.

"The star map from 700 years ago?" Ronan and Bain both came over curiously.

Horse people are naturally good at astrological divination, and no wizard can match them. Even the elders of the clan have never seen the star map from 700 years ago.

"Well, it is indeed a very ancient starry sky." Ronan compared it with the night sky and nodded.

"However, there is a problem." Bain wrinkled his nose and pointed unceremoniously at the southwest corner of the star map.

"The stars here are completely wrong, little pony, did you draw it wrong?"

"Impossible." Rogge looked at it and didn't see any mistakes.

"Hmph. You wizards can only imitate and don't understand what real astrology is." Bain dismissed the pony's answer. If he didn't admit that he was wrong, he would point it out.

"There is a problem with the angle at which the Big Bear is connected. The entire constellation needs to be rotated 15 degrees counterclockwise. The third star is half a star upward, and the sixth star is 1.5 degrees downward."

"And here." Ronan nodded, pointed to the middle of the star chart and said: "Whether it is viewed from the right ascension or declination, this star has to move downward by 0.3 radians."

"Although the star map is from 700 years ago, it was forcibly assembled. For example, the orbits of the stars here are completely unobservable, and their existence can only be predicted through changes in the positions of other stars."

"Ronan, no wonder you have been able to win the Astrology Championship for ten consecutive years." Bain sighed sincerely at Ronan's explanation.

"It's all knowledge my grandpa taught me." Ronan smiled sheepishly.

"We have all listened to the Great Elder's lectures, but none of them are inferior to you. In addition to your talent, you must have put a lot of effort into research." Bain said approvingly.

"Let me mark two lines first." Ronan smiled, pulled the star map closer, and drew on the ground with his spear.

"The first line can be used to calculate the specific time of the star chart from the positions of the lone star of the Ursa Major constellation and the North Star..." Ronan said to himself, and quickly calculated.

"In 1207 AD...the second line was drawn from the Polar Star in the constellation Ursa Minor to the Second Pole Star...to determine the movement trajectory and angular relationship."

After a while, Bain's eyes lit up: "So, these two lines just connect Polaris and Alpha Leo!"

"Yes, we can calculate the coordinates of other stars on the map based on Ursa Major and Leo." Ronan smiled, while Bain helped calculate.

…

"Look here, this reddish star is most likely Sunflower One. Then the stars near it should be..." Ronan muttered something, and soon the entire star map completely changed.

"Amazing! The person who made it is very intelligent." Bain admired sincerely, but he didn't expect that there were also high-level stargazers among wizards.

"What, what, what is all this?" Rogge was confused. He understood every word and couldn't understand even one sentence together.

"To put it simply, the author of the star map set up a puzzle. Little Pony, if you restore it to look like this, the puzzle will be solved." Ronan looked very excited after solving the puzzle, and he was not enthusiastic about Rogge's attitude. few.

"So now that I have the answer, all that's left is the process?" Rogge quickly copied down the answer. The only remaining key was to write the answer on the Golden Snitch.

"Oh, it's almost dawn, and all the sparks are gone. Little pony, it's time for you to leave the Forbidden Forest." Ronan reminded.

"Thank you for your help." Rogge nodded and waved goodbye to the centaur after confirming that everything was correct.

…

"Harry, how could you leave Roger behind!" Hermione looked anxiously at the Forbidden Forest. If Hagrid hadn't vowed that Roger was fine, she would have rushed in.

"Maybe our savior was afraid. He and the centaurs escaped from the Forbidden Forest, but left their classmates behind..."

"Shut up, Malfoy!" Hagrid scolded, Harry's safety was the most important thing, and he didn't care about Slytherin's little wizard at all.

"Hey, are you guys waiting for me to go back for breakfast?"

"Rogg!" Hermione rushed over when she saw Rogge's figure, and Malfoy also stood up straight.

"Roger, do you recognize who that person is?" Harry suddenly spoke, staring at him closely.

On the way back, Firenze talked about the function of unicorn blood. Harry speculated that Snape killed the unicorn in order to obtain blood to extend Voldemort's life.

Roger went to Snape's office almost every day and it was impossible not to recognize him.

"Me?" Rogge shook his head, "I don't know who that is."

Harry took a few steps back in fear. Roger was lying. Why did he lie? Could it be that... Harry looked at the other person in disbelief. Ron was indeed right. Slytherins were all bad wizards and would become that person's Death Eaters.

"Professor Snape may be able to deduce something from the body."

"Roger, did you bring out the unicorn's body?" Hermione guessed it immediately. She hadn't seen the unicorn yet.

"The body of a unicorn! No!" Harry suddenly shouted, taking out his wand and pointing it at him.

"Expelliarmus!" Rogge chanted a spell quickly and knocked the wand out of his hand.

"Mr. Potter, I am free to decide who disposes of the unicorn's body. You have no right to ask me what to do."

"Roger, the unicorn should be returned to the Forbidden Forest. It is part of the Forbidden Forest!" Hagrid's broad figure protected Harry and glared at Rogge.

He had no idea that Slytherin's little wizard would be so bold, not only stealing the unicorn's body, but also attacking Harry.

"Really? Since you are a good gentleman who maintains the Forbidden Forest, then please tell me how those spiders survived?" Rogge meant something, and the wand flashed with a dangerous red light.

He solemnly warned: "Hagrid, if you want to rob, take out your wand."

"Don't even think about using your fists. Maybe you can block a Muggle grenade and not die, but what about Harry?"

Rogge's smile was as hateful as a little devil in the eyes of the two of them. Hagrid stopped with an ugly expression, as if he had eaten an Oriole.

"Assuming you can give me 500,000 gold galleons, I will consider selling it to you..." Rogge smiled. Perhaps in the eyes of Mr. Savior, he was already Voldemort's accomplice.

"Malfoy, what are you doing standing there, do you want to be beaten by them? The Forbidden Forest does not technically belong to the school campus." He called to Malfoy and motioned to Hermione and Neville not to follow.

Gryffindor regarded Harry as a pride, and Roger did not want to put Hermione in a dilemma because of the conflict between them.

"Roger, wait for me!" Malfoy quickly caught up and turned back to Harry with a mocking laugh.
