Broken Sword

I am born with a mystery.

I am bound to this world to do a mission.

My body is dominated by Earth and water.

My soul is controlled by air.

My spirit is ruled by fire.

I am tasked to guard the nature.

And I am destined to kill whoever destroys it.

Who am I?

I am Broken Sword.

They say, I'm a legend.

Some say, I'm a legacy of an ancient civilization. 

Aged for a million centuries,

Cursed to live like an immortal.

I am a deadly weapon made of steel.

I am smoothly curved with danger.

My shadow is tainted with vengeance.

My history is blessed with eternal anger.

Who am I?

I am Broken Sword.
