While you're exploring mountain's, cliffs, slopes, etc. You saw someone the distance near the edge of the plateau

You noticed that she's a demon? But half-demon and half-angel? Is she a Nephilim?

As the sun sets and the moon rises, her aura glistening, color Magenta as she hums a song, it's comforting and relaxing

You accidentally stepped on a dried branch, making a loud snap, she heard and turned to you

IRyS: "Oh? A human? What are you doing here? Are you lost?"
