Twilight: Runes of Eternity

When the Cullen family faces the growing threat of Victoria's newborn army in Eclipse, an ancient and enigmatic vampire from a forgotten age arrives in Forks. Eirikr Hrafnsson - a Viking warrior turned over a millennium ago - carries with him not only unmatched strength and durability but a mysterious, blood-forged magic that channels the power of runes.

Having met Carlisle in his early years, Eirikr has wandered the world for centuries, wrestling with his own morality and the weight of immortality. Now, drawn by whispers of the Cullens' peaceful coexistence with humans, he steps into their lives, offering his knowledge, his power, and his war-forged wisdom.

As tensions rise and the newborn army closes in, Eirikr's presence challenges the Cullens in ways they never expected - disrupting visions, testing loyalties, and revealing the hidden depths of their own gifts. And when the Volturi come, intrigued by Eirikr's rare abilities, the Cullens must rely on him not just for strength, but for guidance through a confrontation that could alter the fate of all vampires.

In a story where history and legend collide with love, loyalty, and power, the ancient warrior must decide whether eternity is a curse to endure... or a destiny to embrace.
