They're honestly not too interesting or important. Just a sith spin off group started by one of Dooku's lesser known apprentices, which ended up losing a lot of it's sources of sith knowledge and more or less winged itself into it's own thing. They're a bit like the Knights of Zakuul, which is probably not coincidental.
