Cover art for Nephilim lyrics by Blind Guardian

From the liner notes by Markus Heitz (author of "The Dark Lands"):

"NEPHILIM" Nicolas is still traveling the spheres. Voices are now speaking to him, a man and a woman, who each want to pull him to their side. She wants to take him to the right path, while he demands allegiance and duty. Good and evil talk to Nicolas in a whisper. How will he decide -- and what exactly is he?
