Runaway

Standing atop the rooftops of tall buildings, it contemplated the sky and its clouds. The bright multicolored dusk glowed and through the cotton candy clouds moonbeams seeped through and illuminated everything with its silver spark.
The entity then started running, running as fast as it could, it ran all the way to the edge of the building and bright feather wings sprouted from its back and ankles, impulsed itself with the wind upwards and landed on the other building, and kept running.
It started going out of breath, but its velocity maintained and it kept running and running and running and then jumping buildings and using its wings to glide. Their wings started going faster and their leaps became longer, their thoughts crashing into each other in a strange nebulous confusion, a mix of colors so vivid and suffocating.
It ran kilometers and at this point the stars were gleaming on the horizon; its once pitch black eyes started burning with an incandescent fire, and suddenly, instead of jumping to the next building, its wings grew larger, and it elevated into the sky, never touching the ground again.
