HEART ~Pure Silver~

First ever twins in elvish history, Yuki and River Hana, princes and heir to the entire elvish domain; and soon to be rulers of Blue Mist Forest. The Silver clan is uniting with the Ember through an arranged marriage, but there's a few problems, Yuki is 18 and the Ember Lord's daughter is younger than the King and Queen had been led to believe. Things complicate more when Yuki falls ill with a sickness no one in Blue Mist Forest yet knows how to treat. Just as things look as if they cannot get any worse, it's discovered that Yuki's younger twin, River may be the fabled Chiyunotenshi. With this ability, can River hope to save his dying brother? Now there's talk of a possible war. A formidable foe, a type known and feared. What happened to the pact the elves had with the Leviathan?
With the possibility of a war starting, after so many years of peace between the Leviathan and the Elves....
We're not prepared for a war. The Leviathan have become so much stronger.
