One grammar mistake/"has" for "have" disenchants not/your stark raven spell.

The moment I read, "Those tales of yore", It brought me back a century into another world. I like that you can use such simple words yet express such lovely imagery. Great work.

"Usher of darkness." Brilliant opening line; the tone is quite suave and sophisticated.

This is five-star level awesomeness. YES

Beautiful and poetic, I love it ]

Thumbs up for this. You took a simple word and turned it into a great haiku.

Powerful and descriptive haiku here. Excellent! Write on.

Great description.

Side note: did you know ravens can mimic like a parrot. It's not common, but it does happen. I kind of think that fact coupled to their black feathers and largeness have resulted in their supersitious label.
