Talk:Demonic Metal Manipulation/@comment-33757548-20180901101346

It may still be in this category, as Demonic Metal Manipulation also covers Corrupt/Cursed/Diabolical/Evil/Hellish/Malevolent/Sinful/Unholy Metal Manipulation, and Stygian Iron could be classed as corrupt or cursed metal, but I think it is more likely to fall under Shadow Metal or Black Metal.
