The Course of 13

Twelve are hidden in the circle
The work is done if they are found
But if you see the course of 13, too
The dream will shatter and you wake up
Madness barks but will not bite
Before it senses your fear
It is a good friend
Who will lead you to your goal
If you follow the 13 without hesitation
And will listen closely
To the circle being secretly completed
If you pledge your loyalty
And never disturb its course
