I´ve recently picked up the work of HP Lovecraft and i am completly amazed by the storys and tales he wrote. You can clearly see where Hidetaka Myazaki took a lot of his inspiration from. Bloodborne particularly has a lot of similaritys and connections to Lovecrafts tales. A lot of taled Lovecraft wrote are about mystical being or gods similar to the great ones in Bloodborne and humans and animals being possesed by them. I can really recommend his books to every fan of the Bloodborne lore and fans of the sci-fi horror genre. And for those who don´t know HP Lovecraft, he is the author of the call of Cthulu myth if that rings a bell.
