The Nightstalker is a one man atmospheric dark metal project. It just recently release A Journey In Hell under Wolfshade records. The music is gloomy, melodic, and full of sorrow. I hear elements of Insomnium among other things. From the band's Facebook page:
"The history of Nightstalker begins at the origin in the group Sercati, black progressive metal. In this formation Steve "Serpent" Fabry, bassist-singer-songwriter, begins to tell the story of the angel. In the first cd of Sercati, we follow the fall of the angel and the search for his place in a foreign world.
But, the character takes another dimension by the writing and publication of a book called "Le journal du Nightstalker" because music, finally, tells a small part of the history of the character and his universe. Steve needs to go further and determine and decide all this in parallel to a personal musical project where he can express all the feelings of his character and his universe."
