"Gone with the Wind" by Blackmore's Night
As Liselle rode away from her first battle, she relished in her insane ecstasy, the thrill of the flames whose light played on the haunted faces of her terror-struck enemies. She touched the axes on her back, bloodstained and slightly singed now from when she'd walked through a patch of flames. Those flames had burned away the last of her true innocence. But she had to keep a mask of the stuff on, unless the sun tore away the shadows if her mask once more to expose her psychotic insanity once more on the battlefield. She grinned devilishly as she recalled how her heart had given her more and more delight at each agonized scream from a dying foe, usually burning as well.
