Talisman servant

It was indeed a bird. It had a pitch-black color and giant wings like the wings of an eagle. It approached the tree from which the window overlooked quietly, and stood staring at me with its blood-red eyes. No, it was not a crow if you had imagined that. Rather, I think it did not look like a crow. No other known bird on earth. It seems to me that he came straight from the heart of hell!! His mouth opened in a loud scream, as if someone was roasting him alive... a scream that violently tore the stillness of the night, almost shattering the glass windows of the house. This thing continued its terrifying screams, until it nearly damaged my nerves and ruptured my eardrums, and I had no choice but to scream as well in order to relieve the pressure of what it was doing to my mind. It was only a few seconds before I lost consciousness.
