Who is Hastur in Lovecraft’s Mythos? What powers does he have?
This is a difficult question because Hastur has appeared in so many works by H.P. Lovecraft and other writers that this overview can’t really be detailed enough to answer the questions properly. Simply put, he’s an antagonist who opposes strong willed humans and uses anything up his sleeve to terrify them and break their spirits. It’s unclear what power, if any, he possesses that defines him as such or not but one possible candidate would be his ability to drive men mad because of their worse impulses or denial of higher truths (such as Azathoth). This just off the top of my head though so I’m not entirely sure if there is a correct answer out there…maybe someone else could help with some of these!
