Last before Legacy. (Doctor Strange #26 Comic Review)

As the final issue before Legacy begins we find Doctor Strange and Zelma Stanton trawling the depths of New Yorks abandoned 76th Street subway on a twofold mission to teach his new apprentice about an ancient temple whilst also on the lookout for more mystical artefacts. What follows is a confrontation with three beings possessed of a seemingly demonic force of Mignolaesque proportions.
