Tragedy.

In some sort of Derelict city, Dexter is in the fourth to top floor of a twenty story building, as he's running up the stairs while it's collapsing, he can feel the ground below him through the ground rumbling, he panics as he runs across the wall over a hole in the ground and grabs a pipe coming from the ceiling and swings up rolling back to his feet on the floor above where he was and keeps on running, turning a corner and heading up some stairs while seeing fire and rubble merging up towards the stair case, as he arrives to the second to last floor the staircase collapses down the shaft of the building and a corner of the building falls off destroying a small bungalow. He looks through the huge gap in the wall then spots a huge 300 foot tentacle like creature with some sort of purple smoke emerging out from it's several breathing spots in it's head, also using a few of it's tentacles to hover over the sink-hole below it, so dark as if it was a bottomless pit, seeing parts of houses, cars and even people trembling into the darkness with blood curdling screams of fear, and even pain.
Dexter's eyes widened and jaw partially dropped open. "It's too late." He mumbles under the panting.
