The vision of Day & Night

As the orange glow faded beyond the horizon,
let darkness reign supreme.
The dancing lights upon the blackened sky,
laughing and the dying glow.
And so rose the brightened beast,
watching over the dancing lights.
But alas,
soon that beast shall be slain.
Killed by the glorious burst of the rays of light,
driving away those cruel dancing lights.
And thus,
the battle has been won.
Without a single blood shed upon the sky.
But then,
the beast shall rise again.

This poem describes the day and night. I describe the sunset and sunrise to be the start of the battle between the day and the night. After the sunset, the night will win the battle. However, after the sunrise, the day will win the battle.
