Pattern is available HERE.

The Brotherhood of the Horadrim, also known as the Crusaders of Light, are only mentioned in the Diablo series. (To my knowledge, at least.) They were an ancient order of wizards and mages that were formed by the archangel Tyrael to combat Diablo, Mephisto, and Baal.

Note that this pattern includes both knitting and crochet instructions. The needle/hook size given above is for the specific craft.
