I finally got all four columns research open and now the decisions to make for choices offered beneath each begin. While I was looking at the console, I picked Elic box at the bottom of Aealic column in order to obtain crystal info.
However, I wanted everything offered and was torn between which to start first, knowing I currently only had enough cyphers to purchase a few. So I thought I would check to see if there was an optional pathway to follow. I found it in Wowhead and decided to share it here for others.
