kaleidoscope.

A dark-colored unicorn with a blue mane and a black horn stands in a swirling purple and blue magical environment, its expression shifting from a confident smirk to a pained grimace as it appears to be under magical strain. The scene cuts to a group of three ponies—green, purple, and blue—reacting with shock and fear in front of a cottage, then returns to the dark unicorn as it screams in pain, followed by a bright flash of light, before ending on a small image of two ponies, one yellow and one purple, looking concerned.
