Moarrrr scribbling.....

When he had time to pause, he looked up at the board, thirteen stones representing almost every heavenly body plus the elements... and they were supposed to cast them onto a circular field no larger than a foot in diameter? Thats bound to get really crowded.

But then maybe that was the point...

Blue eyes scrolled the 13 items listed on the board as he pondered how many sections that circle was supposed to be divided in. Was it supposed to be a section for each stone? Each representation? But the Professor said the circle was made out of a string, he figured this has got to be something simpler, imagine having to divide a foot-long circle into 13 or even 12 parts. Given that this was something totally new to him he raised a tentative hand to reply "Uhm... are they split into 4 sections which represent...." what? Eyes darts back to the board ".... the four elements, Earth, Air, Fire and Water?"
