The rain pounded on the rocky shore of the small island. The storm was always bad here, and the tempest never abated. It was something the inhabitants got used to, along with other, darker discomforts. The island was in the middle of the water, nothing to any horizon. It was dismal island, and cold, terribly cold. Cold enough, even, to turn the rain to slush upon contact with anything exposed too long. And the heavy mist that rested all on the island and the waters around it was impossibly oppressive.
It was this island the boy's body had washed up on. His tattered black hair hung in a curtain around his head, plastered to his skin and rocks by the rain. His eyes were shut but behind the lids were startlingly blue eyes. His body was small, malnourished, and weak. His clothes were a tattered mess on his limp frame.
How did he get there? There was no sign of a ship, there was no sign of any airborne object, and he could not have swum. Any other means were also impossible; the barriers prevented it.
Who was the boy? Not even the boy would know. Almost dead and laced with traumatic mental scars, he would never reclaim whatever mind he had before this island.
What was the boy? He didn't belong on this island, he didn't belong near the island. There were barriers here that should have prevented him from even coming miles around it. He should have thought of somewhere, anywhere, else he had to be but here. Even in his unconscious form his mind was burning from the stress.
Where was the boy? The island was a perfect triangle. Five feet of rocks, sand, and shale stood between the edge of the low tide line and the wall. The wall was six stories tall, twenty feet wide. The wall also served as the building, housing the inhabitants. In the center of the three walls was a large courtyard, two hundred yards across from a tip to the wall across from it. Along the inner walls were stairs that led to balconies on every story, eventually making it to the top of the wall.
Where was the boy? Azkaban.
This Muggle boy was unconscious on the island of the wizard prison.
