The Dark Cliff lies behind the Heavenly City and Palace. This is a completely desolate land, devoid of any life or vegetation.
In fact, the land within the Heavenly Palace itself rarely has any vegetation. So, when Yusuo was very, very young and discovered a Good-Evil Flower with holy blue and vibrant red colors blooming at the edge of the Dark Cliff, she made that place her secret little world.
Whenever she was heartbroken and didn't want to confide in her older sister, Yuqie, she would sit by the cliff, let the wind from beyond the Star River blow through her hair, and gaze at the distant stars hidden within the endless darkness.
Knowing that plants required nutrients to survive, she would, from time to time, secretly steal a portion of the power of Divine Dew from the Human Mother's room.
