A Town of Horror

There was a town, full of people.
But that town was not very simple.

Only 15 people, and they march outside.
Day goes and night comes, and they go inside.

Each day you vote, and you go on trial.
If you are wrong, you get hanged, which ends your survival.
If you are virtuous to others, you show another arrival.

Each person has a different character.
Some are good, some are evil, some are neither.

You don’t know who the good is, neither you know the evil.
If you are the evil, you know who the evils are.

Some goods, knows information about the evil.
Some kills the evil.
Some delays the evil.
Some protects the evil.

The good slowly dies at night, and tries to hang the evil.
The evil kills the good each night, and acts like a good.

Every supernatural beings can be seen till this day.
Except zombies, who really don’t die as they say.

Some are there who does not like to die.
Some are there who likes himself to die.
Some are there who likes someone else to die.
Some are there who wants both, good and evil, to die.

In the end, you win this whole town.
The deads watch as they see.
That the good old folks killed the evils.
And the town will be empty as it is to be.
