They may fall in folds like a curtain drawn across the heavens. The lights usually grow brighter, then suddenly dim.

Answer:
Light of Holy Grail
Here, Holy Grail refers to an amazing atmospheric phenomenon which causes a beautiful dancing waves of light. These lights have different names, such as northern light, aurora borealis. But this beautiful event is shown rather violent historically.
Even though scientists are not what causes this phenomenon in atmosphere, but some researchers explained that highly energized particles from sun enters into Earth's atmosphere at the speed of 45 million mph, but due to our Earth's magnetic field they never crashed into the Earth because Earth's magnetic field deviates the particles path towards the poles and at the south pole there appears a southern lights.
Due to its unique nature and colors, many scientists and sky watchers are fascinated about it. But early astronomers had said that they'd seen shades of evil dragon in these lights.
