Ok, I know this probably ain't very original but meh, I don't care.
Don't want to leave you
Prologue
She sat with her head on his chest, one ear to his chest listening to his heartbeat, sitting in the moonlight. There love was forbidden, but nothing could stop them from having them together. If either one of their fathers found out, they would suffer harsh consequences. Her siblings knew, but they kept quiet. They knew she would do something unthinkable if she was unable to see him.
She was the daughter of Elrond the Half-Elven, Lord of Rivendell. He was the son of King Thranduil of Mirkwood.
They sat there in each other's arms. They were bonded, not by marriage or blood, but by love. If one of them died, the other's life wouldn't be wort living, or if they were taken from them.
There were no words spoken between the two, but none were needed to be, for they were in a deep love, one that would never be broken, not even through death. In fact, she was mute and unable to speak aloud, but she could speak through minds. It didn't bother him at all. She was the one that he loved, and that was all that mattered.
Unlike her siblings, she took after her mother. Her hair was blonde and fair. She looked up to him. He was her happiness. She was never happy when he wasn't with her.
He was leaving as soon as the messages came back, which would probably a month. Neither of them knew for certain, but she was sure of it.
He had recently sat in one of her father's councils that she enjoyed spying on. Even with all the elves that were usually there she was never seen. In about one month, the hobbits would leave and destroy the ring. She didn't want him to leave, but she knew that wasn't for her to decide. That was fate's part.
Ever so slowly, she fell asleep. He took her up in his arms, and took her into her room and laid her on her bed.
He kissed on the cheek goodnight and left.
