I have been listening to the Horus Heresy audio books, which is great until you try looking up characters online who have strange-sounding names.
The character I am trying to identify is from the latest book, The First Wall. So far he has appeared in one scene, but I am unsure if he has been mentioned before this appearance.
The name, as far as I can get from repeated listening, is something like "Folk Sa Aram". However googling that name has not given any good responses.
He is a hybrid between demon and I think traitor legionary, possibly Iron Warriors. In the story he is met by a tech priest of the Dark Mechanicum in the Lion's Gate spaceport. He then uses the priest to hack into the spaceport code. He also seems to have Superman-type eyes, able to melt through metal.
Has this being been seen in previous books? Either something I have missed or forgotten or possibly a book I haven't read yet (I am simultaneously catching up while also listening to the latest releases).
