Mercenary

Don't ask me where I come from,
Do not ask me name.
Stop asking me these questions,
I don't like to play these games.

I come here with a purpose,
A goal that's plain and clear.
A purpose that must be met,
Without hesitation or fear.

There's information about me,
That I know you're just dying to know.
And perhaps I'll tell you some of it,
Just before you go.

My name is not important,
Neither is where I come from.
All you need to know is I'm a mercenary,
And you just met your doom.
