For the people with dark humour only.
There were 1000 characters, and each of them died in some way. Our task is to describe, how did it come to this, by substracting one from the number of person before us. Something like this:
Person 1: Character number 1000 tripped on the wire and fell from of stairs.
Person 2: Character number 999 drowned in a bathtub.
So, as for the beginning…
Character number 1000 choked on gristle while eating a chicken.
