No just your spelling. His name is Horus. Like the Egyptian god of death war. There's LOTS of religious symbolism and allusions in the material. WH40K is a satire of so many real world things so you will see stuff in the series and ask "XYZ? like the real world religion that involves XYZ??" And the answer is usually yes.
Just a small correction: Horus is not the god of death, but the god of ruling, war and the sky. The role of god of death fits better to Anubis or Osiris, depending on how you interpret the role.
My husband listens to 40k audiobooks to go to sleep and they’re typically at about a dean koontz level- surprisingly good from my perspective, because I’m expecting fanfic levels of skill.
