Fire
The will of fire is strong. It never retreats or gives up, but moves on, again and again. Forever it goes, forever it burns.
It eats up all those it burns, but those left are not in ruins. They grow back easily and quickly. Even after the fire has passed through the trees touching each leaf, the trees will grow and their leaves will flourish. For out of the ashes, something beautiful will arise.
But eventually it will burn away. Eventually it will die.
And after the last flicker of flame falls to the ashen earth, we are left cold.
