In Hogwarts, 5 years have passed since Edmund's terrible reunion with the train station (which he hoped would never see again once he became the King). Hermione and her fellow friends, Harry and Ron, were no longer immature first year students, but somewhat mature sixth year students. By this time, Hogwarts was in an amiable relationship with Narnia and its rulers. It was mostly Queen Susan who came yearly and stayed for a week or so to plant good impression about Narnia into the minds of the magical students, who could become valuable allies later on.
The weirdest thing of all was that when the Old Kings and Queens of Narnia were in England, Hogwarts' time flowed along with England, and when they were in Narnia, Hogwarts' time would fly the same as Narnia as well. It was truly magical. Thanks to this weird time flow between Hogwarts and the Narnian royalties, Queen Susan, during her visit, never looked abnormal in the eyes of the students and the faculties of the Hogwarts.
On one cool November evening, during the supper banquet, Professor Albus Dumbledore clanged his glass to get his students' attention.
"Students! I have a brief announcement. Today, I have received a news from Narnian court that due to an inevitable reason, Queen Susan the Gentle will not be able to delight us with her visit this year."
At his words, a lot of male students could not hide their disappointments, for Queen Susan's beauty rivaled that of beauxbatons students.
"However, we also received an honor of having a different royalty coming in her place. I believe he never visited us since five years ago, and he was, then, I dare remember, a brave little man."
Everyone, including the sixth and seventh year students who could hardly call back any memories of a little boy, anticipated Dumbledore's words, whispering here and there, guessing who it could be. The recent history lesson had taught them all that Narnia was now ruled by five kings and queens. If the visitor is "he," then he could not be Queen Lucy, the only remaining female queen after Susan. Thus, the name of Peter, the High King, and Caspian the Tenth started to spread. Professor Dumbledore patiently waited until he was sure that his name was also mentioned. Finally, when students began to whisper the name "Edmund," he cleared his throat to silence them all.
"As many of you have guessed, this coming year, we have the pleasure of meeting King Edmund the Just, Lord of the Western Woods."
Another burst of whisper spread throughout the great hall, for nobody has ever seen the said king. Of course, there were words about his wisdom, great judgment (his title, "the Just," suggested so), his realm over the woodland creatures, and lots of other things. Albus Dumbledore once again cleared his throat to continue.
"His Majesty will visit us during the same season Her Majesty Queen Susan had been visiting, which is this coming month. Please welcome him with the warm, traditional Hogwarts welcome so that we faculties won't be ashamed to represent you all in front of his presence. That is all for tonight."
Then he sat back down. The banquet hall immediately erupted into a mixture of both hushed and excited conversations. Among them was that of the famous trio also.
"Too bad Queen Susan won't be here this year. Wonder why she can't come?" Ron began.
"I don't really mind any other royalties visiting as long as they are nice like her, or, at least, without too much pride." Harry commented. He clearly had Slytherin in his mind, their arrogance of being the pure-bloods of Hogwarts.
"I don't care in any way. It's not like we're going to be talking to them or anything." Hermione quipped in. She kept her gaze at her foods. Truly, she was not interested in the royal visit at all.
"Come on, Hermione. We need Narnia. Haven't you heard what Professor Binns said? The Narnian kings and queens are the only one that could control those centaurs and you know what else." Ron smirked as he casually tossed a berry into his mouth.
"Ron's quite right. According to Professor Binns, the nature itself has been serving them as their sovereign rulers. They could be a great help when we are in wars or something." Harry looked at Ron with a grin.
"Oh, shut up, you two! You know full well that I never miss any of the professors' words! Of course, I know they are essential for future. What I'm saying is, in the end, it is not us, but the professors who leave impression on the Narnian." In annoyance, Hermione ferociously chewed her piece of bread.
"We'll see if King Edmund the Just is any different." Ron, grinning along with Harry, concluded, ignoring Hermione's exasperated grunt.
Edmund was quite depressed when he found out that he was to visit Hogwarts from now on, for the lifetime, not just this one time, because Susan was pregnant with Caspian's child and wanted to focus on nursing the child. It was Peter's order. Of course, at first, not knowing he was tricked with clever words, Edmund agreed to go in behalf of his sister who bore new life now. Then, after fully agreeing with Peter (he thought it was strange how Peter was repeatedly asking for "Yes"), he found out that he agreed to a life-time errand.
From what he remembered many years ago [a.n. Hogwarts time went back when Pevensie's went back to the reality the first time. To Edmund, Hogwarts was what he visited long, long time ago since he was grown up when he returned to reality.], his very first time at Hogwarts was not so pleasant. From the train station to that annoying girl and too many people at welcoming ball (he detested balls), Hogwarts left a very bad impression in his mind. Too bad, it's happening. He told himself. From past lessons, Edmund learned that holding grudge was not a wise idea.
Time flew like arrow for the next several weeks. Edmund was too busy handling all the legal documents of the country that he hardly noticed when the day of departure came. Lucy had to burst into his personal library (he was the only one with a personal one), and thereby greatly annoying him, to remind him that he was to leave in a few hours.
Two centaurs whose name Edmund had not yet learned, Trumpkin, and Pattertwig were to accompany him as well as two Telmarine soldiers who became loyal to the monarchs after the war. Edmund grunted. Peter still thought he needed protection (over-protection), and he was already eighteen! Regardless his disapproval, he thanked the High King and kissed his sisters good bye. There were knowing nods and looks passed between him and Caspian. Finally, he climbed onto his horse, Demetri, and left for the dreaded school of wizardry.
The trip was expected to take about five to six days. Most of the time was spent to cross the Great Plain that separated the lands in which Hogwarts and the New Cair Paravel existed. What Edmund did not expect from the trip was extreme wetness caused by a heavy rain storm. The trip was going to take a bit longer than he expected.
