While so far, the Death Eaters had contented themselves attacking the homes of muggleborns, one Friday in May, they suddenly decided to attack Hogsmeade.

"Tomorrow morning, he students will be in the village at ten o'clock at the latest, so that's when we're going to strike," Lucius Malfoy informed his fellow Death Eaters.

'Oh, that's why he didn't invite Uncle Severus for tonight's meeting,' Harry realised. 'He doesn't want him to know about it in advance and warn the headmaster.'

Only later, when he was lying in bed, a sudden thought crossed his mind. 'Maybe I should warn Ferdinand to not go to Hogsmeade. I wouldn't want him to get hurt, and there's no guarantee that I'll be able to help anyone.'

He almost decided to telepathically contact his brother, when he recalled that Ferdinand was younger than himself and not even a Hogwarts student yet. 'Ah, thank Merlin I didn't contact him,' he thought in relief. 'I should have thought about that earlier instead of unnecessarily worrying.'

As usual, Harry joined the Death Eaters to get to the site of the attack by Portkey, before he turned himself invisible and assessed the scene. 'I don't know why they want to attack here,' he thought in confusion. 'I can understand the muggleborn families, even if I think that we should just leave them in peace, but I don't see any reason to attack the village here. No one here did anything to them, let alone to Father.'

He decided to just remain in the back and observe the battle, resolving to only interfere if he had to save a child.

Watching the Death Eaters fight the shop owners along the main street, Harry almost regretted that he had come to Hogsmeade at all, when he observed how a group of five Death Eaters began to attack two students, who were peacefully wandering along the street.

He quickly apparated closer to the scene and, realising that the five Death Eaters were repeatedly casting nasty, dark curses at the two boys, which would kill them if he did not interfere, he quickly jumped behind the boys, so that he could grab one arm of each of them in order to rescue them.

Just when he readied himself to apparate and thought 'To the hospital wing at Hogwarts,' his left shoulder exploded in pain. However, he did not waver at his disposition and quickly brought the students to safety. An instant later, they found themselves on the floor of the hospital wing.

"What was that?" one of the students asked the other. "How did we come here?"

"I don't have a clue, but it hurts," the other replied, groaning. "I only know that it should be impossible to apparate right into Hogwarts."

"I'm sorry," Harry replied in a small voice, unconsciously letting out a moan at the overwhelming the pain in his shoulder.

"Who are you? Are you hurt as well?" one of the students enquired, just when the healer headed over to them in a fast pace.

"Mr. Weasley, Mr. Wood, what happened to you?" she asked, eyeing the students' obvious injuries in apparent disbelief.

"Death Eaters attacked Hogsmeade," one of the students replied, pointing out that someone, who seemed to be invisible but apparently in pain, had apparated them right from the scene to Hogwarts.

"Very well, both of you make yourself comfortable on a bed, and you, Mr. Invisible, please either make yourself visible or wait here until I'm finished with these two, so that I can look after you."

"All right," Harry replied in a small voice, knowing that he needed help. 'I can't show them what I look like,' he thought. 'They'd know immediately who I am. But the healer won't be able to heal my shoulder like this.' He took a few steps in the direction of the healer's office, where he could lean against a wall, trying to not panic, while his thoughts went haywire. 'Oh,' he suddenly thought, 'as a healer, she should be bound to a healer's oath. I'll ask her, and if it's safe that she won't give me out to anyone, I can make myself visible, when no one else is around.'

Finally, the healer came towards the spot, where Harry had arrived with the two boys, and Harry saw that both boys seemed to be fast asleep in their respective beds.

"Now, first of all, thank you for saving their lives," the healer told him. "They'll both be all right over time, thanks to you. Now, it's your turn. Please make yourself visible and let me heal you."

"Excuse me, but can you promise me that you won't tell anyone about me?" Harry asked in a soft voice, causing the healer to stare in his direction in apparent surprise.

"I'm a healer, I'm Poppy Pomfrey by the way in case we haven't met before, and I'm bound by my healer's oath to keep my patients' secrets to myself. I assure you that I won't give you out to anyone," the kind, older lady promised in a gentle voice.

"All right, thank you, Madame," Harry replied and slowly made himself visible, causing the healer to stare at him in disbelief.

"Come with me," she instructed him in a no-nonsense voice and led him through her office into what seemed to be her private quarters, where she motioned him into a bed. "This is the guest room in my private quarters, so you don't have to fear that anyone will walk in," she said in a soothing voice, before she turned into healer's mode and waved her wand over him multiple times.

A sharp pain shot through his shoulder, before the pain vanished altogether. "There you are," the healer said, smiling, as she handed him a phial. "Drink up. I'll prevent your shoulder from getting infected. Now, will you tell me what you were doing in Hogsmeade and how you came across Messrs. Weasley and Wood?"

"Do you know who I am?" Harry enquired.

"I've heard about you," Pomfrey admitted. "Your birth parents are quite desperate. I've also heard from your unofficial godfather that you're extremely proficient at brewing potions and that he hopes that you'll assist him again like during the Christmas holidays."

Harry let out a deep sigh. "The Death Eaters usually want me to participate in their raids," he admitted, "but I only always accompany them in order to save the children."

"That's you!" Pomfrey blurted out in apparent excitement. "They were looking for you in the Daily Prophet. I think they're almost ready to award you the Order of Merlin for saving all the children, which you rescued."

Harry chuckled. "I don't want anyone to know that it's me who does this," he informed the healer. "Thank you very much for healing me, but now I have to return to Hogsmeade, before the Death Eaters miss me."

"Harry," Pomfrey said, while he slowly got up, shooting her a grateful look for not only healing him but also mending his torn robes, "will you decide to attend Hogwarts from the next school year onwards? I'd be very happy to have you here, and if there's anything that I can help you with, just come to see me. I'll never forget that you saved so many students' lives."

"Thank you, Madame," Harry replied, as he readied himself to apparate.

"Harry, wait," Pomfrey stopped him. "You can't apparate in and out of Hogwarts. I don't know how you managed earlier, but…"

She trailed off, when Harry chuckled. "I can," he reassured her. "I can, because I'm the heir of all four founders. I'm the heir of Gryffindor and Ravenclaw through my birth father and the heir of Slytherin and Hufflepuff because of a bonding spell which Lord Voldemort cast at me when I was a baby." With that, he quickly apparated back to Hogsmeade, turning himself invisible as he went.

Thirty minutes later, Poppy Pomfrey had to defend herself not only against the parents of Oliver Wood and Percy Weasley but also against the headmaster. "I'm sorry, but the boys' saviour asked me to keep his identity a secret, and since I'm bound to my healer's oath, I can't tell you who rescued them.

"But he or she saved Percy's life, and we want to at least be able to thank them for what they did," Mrs. Weasley said, slowly raising her voice in an unpleasant way.

"The Weasley family owes him a life debt," Arthur for once approved his wife's rant, causing the Woods to nod their agreement.

"Poppy," Dumbledore asked in a calm voice, "was it a Hogwarts student?"

"No," Poppy replied and smirked, thinking, 'And even if it was, I wouldn't tell you, Albus.'

When Harry returned to Hogsmeade, the fight was still in full swing. He observed for a moment how a small group of Death Eaters were fighting two men, 'Probably professors,' when a sudden thought crossed his mind. 'One of the men is the spitting image of Ferdinand,' he realised, only to add, 'and myself. He must be my birth father.'

With a combination of disgust and interest, he watched how the two men were keeping themselves against six Death Eaters, before he continued to walk along the main street to see if any other students were in trouble. Not feeling energetic enough to apparate anyone else away from the village, he contented himself to cast a series of stunning spells in a fast pace at a couple of Death Eaters who were randomly attacking children, making the students look around to thank their invisible rescuer in vain.

After a while, he returned to the scene, where his birthfather and his colleague were still fighting four of the Death Eaters with the two others lying on the ground, unmoving. 'They're not bad,' he thought, still torn between annoyance and curiosity. Knowing that at one stage, he had to make himself visible and show the Death Eaters that he was with them, he cancelled his charms and cast two quick stunners at the teachers, who could not help but stare at him with apparent surprise and even shock until it was too late.

'I guess they recognised me,' Harry thought in amusement.

"Thanks, Dark Prince," one of the Death Eaters told him in obvious relief. "Potter and Black are really tough."

"You're welcome," Harry replied, smiling, while his thoughts went haywire. 'Black,' he thought, 'where have I heard that name before?' It took a moment, before he recalled, 'Oh right, that's what Ferdi told me to be our godfather.' Stepping over to the two men, he looked at them in disgust, before an idea crossed his mind. Training his wand at the professors, he cast a spell that made them hover upside-down in the air, before he added a charm that made his victims move along the main street towards the Hogwarts gates.

'Oh well, that was fun,' he thought, as he finally apparated home, realising that the Death Eaters seemed to have left already.

The invisible saviour who had at least saved two students' lives and had rescued dozens of students from Death Eaters' attacks as well as the boy who had attacked and ridiculed two of the most popular professors quickly became the topic of the weekend at Hogwarts. The teachers had only been released from their predicament by the help of the head girl and head boy in front of the entrance doors to Hogwarts, while more or less the whole student body was watching the scene with interest.

"That was Harry," James told his wife, who stared at him in shock.

"James, are you really sure? Why would he do such a thing?"

"Absolutely certain," Sirius spoke up. "He probably did it to support the Death Eaters. Six of them were attacking us, and after quite some time, we only managed to bring two of them down. They were really good."

"Maybe he didn't know who you were," Ferdinand spoke up in a faint attempt to prove his brother at least innocent of willingly harming their father.

Sirius let out a snort. "Even if he might not have known me, your father is the spitting image not only of you but also of Harry. He must have known, especially since he has met you before."

"Of course he knew," Lily spoke up, her voice laced with disbelief, disappointment and anger.

"He didn't physically harm you though, and he ended your fight with the Death Eaters, who possibly could have really hurt you otherwise," Ferdinand voiced his opinion.

Lily could not help smiling. "You really like your brother, don't you, Ferdi?"

"He's amazing," Ferdinand replied, grinning, before he headed to his room to write a letter to Harry.

The response came only after Ferdinand had already gone to bed, and Lily hesitantly took the parchment from the black raven, letting out a gasp as her eyes fell onto the few words scribbled onto it.

'Hi Ferdi,
Because I could and because they're not family but enemies.
Greetings
The Dark Prince'
