He was alive, it appeared, but only just. Zeph limped slowly over to where Harry lay, bleeding heavily on grass that was as much red as green. Voldemort he could see was dead; wizards were already preparing to incinerate the body. Ron and Hermione were kneeling by Harry, both crying as they said what they knew must be their final farewells. They drew back slightly as Zeph came over, wary of the strange, otherworldly boy. Zeph could see the dying boy's face growing pale, and almost translucent.
"Stay away," Ron said warningly. "I'm warning you."
"Ron," Harry said weakly. "Let him through."

Zeph found himself caught in Harry's gaze, looking into eyes that looked too old and sad to belong to a boy of seventeen. At last, he was released and Harry smiled faintly.
"I'm as safe with him as I am with you. Zephyrinus would never do anything against me, or against my beliefs, and he's already saved my life once."
"Harry," Zeph said solemnly and meaningfully. "Is there anything I can do?"
"Kneel down, that's it. Hold my left hand to your forehead and put your wand in my other hand."
"Okay," Zeph said, not understanding at all. When they were sorted, Harry said as firmly as he could manage.
"Zephyrinus Potter filius meus ist."

The wand sparked and shot of energy flooded into Zeph's body through the hand he was holding to his forehead. There was a searing pain in his forehead and he gasped.
"Harry! Are you okay?" Hermione asked anxiously.
"I'm as well as I'll ever be. Carry on my work for me, cousin, and don't be sad because I'm going to see my parents and Sirius again at last. Zeph, if they start crying, hex them. I think you'll fit in very nicely at Hogwarts, and you'll be having especial fun in Defense Against the Dark Arts, mark my words. Goodbye, you lot, live long lives and be happy, or I'll come back and haunt you." Then the last light left his eyes, and Harry Potter, the Boy Who Lived, died after a battle on a field stained with blood.

Zeph wiped his eyes, and watched as Ron reached slowly out and shut Harry's eyes for the last time. Harry's two friends made a noticeable effort to pull themselves together and not start crying, but they managed it even if they did look very pale. Dumbledore had fainted, and was lying a few meters off. A couple of medi-wizards were already with him.
"Are you always like that?" Hermione asked.
"What? The silver? No, I'll sort it."

Zeph tapped himself with his wand and the colour flooded back into his body. The older boy and girl stared at him.
"Harry," Ron said quietly. "Blimey, you look just like Harry!"
"I do?"
"Yes," he continued, looking like he'd seen a ghost. "Black messy hair, green eyes, scar - its all there."
"Well, I guess we must be cousins or something, that's what he said. We'd better get everyone to Hogwarts, no one else will be able to at this point."

That was perfectly true. The participants in the battle were either collapsed on the grass having their wounds attended to by healers that someone had fetched, or cremating the bodies of those less fortunate on both sides. Zeph pulled himself to his feet and picked up a length of rope that the Order had used to get everyone to the right place.
"Portus!" he said, tapping it. Then he went over to the old Headmaster. "We won sir, it's over."
"But we lost Harry," the wizard replied, looking ancient and grieving. "Take us home, Zephyrinus. I put us in your charge."
"Yes sir, he said he'd be happy now, with his parents and uh Sirius?"
"He will be, but that doesn't make it any easier." Then his eyes rolled back in his head and he fainted again.

Zeph sighed. Why did Dumbledore think he should be in charge of everything.
"Kent!" he called into the silence. "Would he and four others stay and see to the bodies, please. Everyone else come over here please, we're going back to Hogwarts on Dumbledore's orders."

As the others came crowding over, he draped Dumbledore's arm around his shoulder and with Ron's help managed to get him upright. Hermione and an Order member were carrying back Harry's body. Cub and Rocky were the first to join them, and soon relieved Zeph of his burden. When everyone was holding on, Zeph activated the portkey. They shimmered for a second, then vanished.

They appeared en masse in the middle of the lawn just outside Hogwarts School of Witchcraft and Wizardry. A crowd spilled out of the old castle that Zeph had previously seen only in his dreams. He stared at it wonderingly. Students (and teachers) stared openmouthed at those of the Lost Boys who hadn't changed to their normal colours again. Well, they did look a bit zany.
"We won!" people were calling from the crowd. "Voldemort's dead at last!" One of the teachers came rushing over.
"Albus!" she said, rousing Dumbledore anxiously from his unconscious state again. "Are you all right? Is You Know Who dead? Oh my God, Harry! He's in two places."
"Please calm down, Professor McGonagall," Zeph said calmly, knowledge flooding into his head from some unknown source. "I am Zephyrinus. The war is over and we won. Harry died killing Voldemort, but he is at peace now and told us not to grieve because he is with his parents. He died with the knowledge of victory and thought his sacrifice a small one for what it achieved."

Then the last remnants of his dwindling energy failed him and he pitched forwards onto the soft ground. People rushed forwards to grab him. As he was levitated gently in with the other wounded, the last thing he heard before drifting into unconsciousness was a discussion about enrolling them formally at Hogwarts. Zeph was going to school at last.
