Le Seigneur du silence

When the great hero of the city of Idriss is murdered, Vidar, the Lord of Silence, must take his place as chief defender against the mysterious terrors lurking in the dense forest beyond the city's walls.

Vidar is a man tormented - by a lost memory and a vampiric jewel that demands the life energy of others.  Now, with a killer loose within his home city, Vidar must solve a three thousand year old religious mystery to unlock the terrifying secrets of his own past.
