A Poem to set the mood for my first post

A trumpet blast and a flowing cape,
Adorn the golden plate.
A reign of terror in which evil will drape,
A pitiful child as bait.
The noble knight comes to inspect the scene,
All which seems like a terrible dream.
His corpse should soon rot green,
To fill Fate's imperfect seam.
Finally a great ambush was set,
For this one unsuspecting hero.
Death came to the trap setting quartet,
As all were shot through with only one arrow.
The hero took over and made a worse upheaval,
For who is good and who is evil.
