Lorgar, Lorgar, Lorgar. I won't say much to not spoil the ending but *sighs* Lorgar, how far you have fallen in the glory and admiration of the writers and community.
The story is fine, not too exciting but we do get glimpses of just how badly the traitor legions have bled trying to usurp the emperor, and why Horus took such a massive gambit in the final siege of Terra, why such recklessness had to be employed, they simply lost too much, as much as the loyalists.
The pacing and dialogue is fine. Nothing is TOO amazing nor eye rollingly cringy.
But the ending.
Oh, Lorgar, how sweet it is to see you get exactly what you deserve.
