I’ve heard very conflicting things about him ranging from just essentially a greater daemon to a minor chaos god. Is he capable of making deals like the big four? And to what extent? Does he have his own demon host or is it just him? I’ve been working one some homebrew csm who are loosely aligned with him and was wondering how much he is able to interfere with or empower other beings both inside and outside of the warp.
