How does a filly cope with loneliness without the father who ran out on his family, leaving Starlight Glimmer without a daddy and her mother a broken, bitter shell of her former self? And now that her best, and only, friend has been flung off to Canterlot, who does a filly have to turn to? Nopony but herself with a growing, twisted mindset and nopony to steer her in the right direction. This is her start of darkness, leading her to what she would one day become.
