Black spirits and white
Red spirits and grey
Harken to the rune I say.
Four points of the circle, weave the spell,
East, South, West, North, your tale to tell.
East is for red for the break of the day,
South is white for the noontide hour,
In the West is twilight grey,
And North is black for the place of power.
Three times round the circle's cast.
Great ones, spirits from the past,
Witness it and guard it fast.
