The thing I love the most about Perturabo is that he doesn't really hold grudges, despite his temper, his grumpy demeanour and all that, he is waaay to forgiving.
He didnt keep a grudge for his foster brother Andos when Andos beat him in the art competition(despite in his rage destroying the artwork, and his relationship with his brother). And not only that, he openly admitted to other people that Andos was better than him, at art, and as a human and was surprised and disappointed that Andos wasn't named Tyrant after their father's death.
Perturabo forgave Fulgrim for lying to him and almost killing him and stealing his soul. He forgave him enough to fight beside him at Terra. He wasnt happy about it, but he didnt make a fuss.
He has been forgiving Abaddon time and time again and has helped the war effort of the long war
Perturabos reputation as unforgiving and cold is undeserved. Just let the guy mope for 15 minutes and he will bounce back.
I do wonder if he even truly hates Dorn or if he just wants to challenge himself enough to beat him and is too uncharismatic to express himself.
Also including an AU where Lilith pursued the priesthood. The brilliant brainchild of tech priests employing cats to keep rats away from the cables belongs to @darka-art & @holylustration respectively.
The Konrad Curze flashbacks in the Night Lord series are so funny, Curze is just sitting there sobbing into his hands going "I hate all of you so much" and Talos is just standing there making a 🥺 face thinking "You Are My Dad"
