Standard disclaimer: The universe of Earthsea was created by Ursula LeGuin. I make no claim to anything but my personal reading of her work.
The half that is yours, the half that is mine… she remembers how the fragments had ceased even to look like metal. Crusted with dirt, salt and blood, separated across eras of the world, across continents out of mind over the sea, and one of them buried for centuries in the dark. Yet they had sprung together as though recognizing no time, nothing but the answering curve of their fellow. Laid together in her palm, and then the circle, whole.
"What is it, love?"
Tenar shifts, to feel the full length of his body against her own.
"Magic," she says.
