The Dark And The Light

I bet you thought you knew faeries. I bet you thought you knew elves. But let me tell you something.
You have no idea.
Leilah is a dark faerie. Mistivious, mysterious, and beautiful.
Rose is a light faerie. Sweet, kind, and lovely.
The two are best friends, and are the most powerful faeries in their land.
Leilah is one of the last dark faeries left. Although she is a dark faerie, she has a kind side as well, and is always loyal to her friend.
Rose is brillant, brave, and sometimes has a temper.
Things are not well in the Kingdom though.
The Dark Elves are growing in strength and number, and are determined to either crush the faeries or rule them.
The dark elves have heard of Rose and Leilahs beauty and strength. Now they are willing to strike a deal. If the two will marry them, in return they will unite the Kingdoms and not attack their lands.
If they don't agree, they will kill everyone.
But the dark elves have underestimated the power of a a dark faerie.
