A bizarre little rhyme

One by one they all shall fall, and through it Chaos will be stalled.
By light of day and dark of night, the two shall forever simply fight.
And in a discord somewhat fair, shall find that friendship may have flair.
The darkest moment shall arrive, when five look down but one should derive.

The purpose of all is to be a stone, to be stepped on, wiped and paid as a loan.
The six shall see, with eyes ever green,
That all recieve justice, no matter how unclean.
