Harry and Luna stepped out of the Leaky Cauldron. Despite having lived their lives once before, walking around in the middle of muggle London without being in constant combat or danger of detection was a novelty for them.

They walked along, window shopping and simply enjoying the day. They had finished all of their school shopping earlier in the day in Diagon Ally.

Cars zipped back and forth along the road. The sun was shining. Luna sighed in contentment as she laid her head on Harry's shoulder.

The pair of "children" walked down into a subway station; they really had no set destination in mind.

When they reached the booths, Harry discretely waved his wand and the ticket seller let them through.

They wandered down to the tracks, and sat on a bench. On their right the bench was empty, while on their left a group of four muggle children were waiting with their luggage.

The platform was rather crowded, and, after a few minutes the pair of magic users got up and turned to leave. That was when they felt it.

A deep shudder ran through the entire terminal. It was magical, both Harry and Luna felt it. But it seemed none of the muggles did, none except for the four muggle children who had been sitting to their left.

As Harry and Luna drew their wands and scanned the area for threats the four muggle children stood up, obviously tensing. Harry and Luna covered them with their wands.

The oldest, a boy who looked to be thirteen or fourteen, called out. "Hold hands, and don't let go!"

Harry and Luna had no idea what was happening. The magical shuddering was becoming more pronounced.

"Harry" Luna said a tad nervously. "Any ideas?"

The four children looked over at them, and Luna gasped. Harry's eyes snapped to Luna for an instant, then, realizing where she was looking, snapped his eyes and wand back to the four children. Harry was no longer so sure they were muggles.

The children seemed to have no idea why only Harry and Luna were feeling the magical pulses aside from themselves.

It all happened in a heartbeat. One moment the four children were standing there nervously, as if anticipating something. In that same moment Luna gasped and the magical pulses seemed to reach a crescendo. The next second everything was calm, the magic was gone, nothing seemed to have changed, nothing except the four children.

They were no longer waiting for something, they were far more relaxed. Their bodies seemed more vital, and most important, they hand changed position. One second they were holding hands in a square, the next they were all facing Harry and Luna in a line.

"Harry they are like us" Luna said quietly.

Harry turned to look at her. "Like us how?" he asked softly, keeping one eye on the children who had just changed so dramatically. It was not that anything had changed physically, but somehow they suddenly seemed older, wiser, more alive seemed to be the right word.

"Harry they have lived through more than one lifetime, just like us" Luna whispered.

Harry's eyes flew open in shock. "Then I guess we had better go and say hello." Harry said finally.

Harry and Luna sheathed their wands and walked over to the four children.

The children for their part were looking at Harry and Luna in confusion, and not a little bit of astonishment.

Harry walked right up to the oldest and held out his hand.

"Harry Potter, Boy-Who-Lived, leader of the Order of the Phoenix, former defeater of the Dark Lord Voldemort" Harry said.

The older boy's eyes widened and as he took Harry's hand he said

"High King Peter the Magnificent, ruler of Narnia, defeater of the false king Miraz." The boy replied.

The two boys who were truly men, shook hands.

If I get enough reviews I might continue this story. Just to be clear. The Pevensie children when through the whole of the Prince Caspian book between heartbeats here, that's what made the change.

For the record ages biologically, Harry is 12, Luna 11, Peter 14, Edmund 12, Susan 13, and Lucy is 11.

Tell me what you think, and tell me if I should continue.
