The Darkening - Ran Cartwright - Bog

There are two swords long thought to be fable. One is the Zyn Blade, legendary sword of the centuries dead King of Zyntrolm, Ilian Zyn. The other is its more powerful sister sword, the Korlan Sword, both forged by the legendary Venenae sorcerer, Korlan. Shown the location of the Zyn Blade in a vision, King M'lerek Zyn retrieves the sword and decides that if the Zyn Blade exists, so must the Korlan Sword. The young king sets off in quest of the Korlan Sword. Little does he know that dark forces are gathering far to the north in the Gnydron nation of Shokkuhl, forces that will set in motion a time known as The Darkening. So it is written in Vergama's Book of Destiny.
