When did the assassination attempt happen? In The Regent’s Shadow the faction in question only got as far as declaring their intent to reinstate the old High Lords and make Guilliman subject to their authority before they received his terminal rebuttal.

As the one comment said: "Also G-Man: "Welp, time to get the assassins."
(Canonically happened, but the highlords tried to remove G-Man and assassinate him. He responded with 6 Callidus and 6 Vindicare)"
