Do you have any information on this course? I can't seem to find anything about it and I think it would be quite interesting.
I'm not sure what you mean by course? Do you mean 'path'? I do want to answer this question, but its unfortunately a bit too open-ended at the moment!
EDIT: Actually. I think I know what the author means, now. I'll explain how I formed this conclusion and re-answer this question shortly.
EDIT #2: I was wrong! THE WILL OF THE MAGICIAN FAILED! DAMN YOU, ASTRAL DOUBLE THAT I THOUGHT WOULD EXPLAIN SHIT! YOU HAVE FAILED ME! BE ACCURSED AND RESIDE IN THE ABYSS FOR FAILING! BWAHAHAHAHA.
Err. I talked to myself, and got the answer wrong. Blast.
