Tear Jerker / The Coffin of Roboute and His 20 Sisters

• Roboute Guilliman, a superhuman who couldn't help but constantly lamented over what happened with his brothers. He was able to understand and felt sympathy for his traitor siblings, realizing why they had turned traitor.
  • With Petra, he felt sympathy for her as she was constantly observed by the Eye of Terror
  • With Kassandra, feeling saddened by how a young child had to fend for herself and eat animals raw. Doubly so as Roboute recalled how he would go along with Russ' jab at Konrad's antics out of courtesy.
  • With Aurelia when he found out what Kor Phaeron had been doing to his younger sister as the woman was able to grow into a full grown adult at the ripe age of seven months old by Terran standard years. Roboute felt sick as he realized had he come later, Aurelia would have turned out much like her canon counterpart. Roboute felt even worse when he recalled Kor Phaeron in his old timeline was elevated to Lorgar's closest aide.
  • With Morrigan he understood her plight.
• Kassandra ( Primarch of the Night Lords). A prime example given her background. Same like her canon counterpart, Kassandra was forced to kill for food and lived in squalor. She was forced to eat a dog raw, one she personally killed. When she was offered simple food by Roboute, she wept endlessly.
• Aurelia ( Primarch of the Word Bearers). Aurelia like her canon counterpart was abused by Kor Phareon and placed under strict scrutiny. There is a heavy implication and by Word of God that Aurelia was raped by the Colchian men as one of her many punishment.
  • Made even worse when it becomes clear in Aurelia's pov chapter that she thinks in her mind that she deserves to be punished, for letting them hurt her, for selfishly taking advantage of her brothers kindness, and only isn't because her brother loves her.
• The Exodites have shown us just how kind, mirthful, loyal, honorable, and generally good the Eldar actually are at heart. But when faced with tragedy and stress, they're forced to channel the essence of Asuryan to hammer down their emotions and turn themselves into cold, unfeeling things of near-pure (but very much not necessarily unbiased) logic, with no warmth to be found, only dispassionately viewing everything and everyone around them as tools and an excessive amount of selfishness - a personality set that's hauntingly familiar to anyone with even a passing knowledge of 40K Aeldari as just being their default, if not only state of being. That is to say, the Elves of the far future have not only lost their homeworlds and their hope, they've also lost everything that made them good people through something like fifteen millennia of unrelenting trauma.
• Malekith is a very old Aeldari, dating back to the tail end of the War in Heaven, and before his exile was the lover of Lileath - yes, that Lileath. Anyone with basic understanding of what happened to the Aeldari knows just how badly this ended - and how rough it would have been for a long time leading up to the end what with Asuryan forcibly cutting the gods off from mortals in an attempt to appease Khaine. Naturally, Malekith is very much not okay over this and has had to keep some of his emotions on total lockdown ever since the Fall.
• It's very subdued, and very brief, but when the Emperor finally meets the Avenging Son, the first thing he does is ask for his sword back momentarily, whereupon he takes it in hand and psychically attunes himself to the imprint of his future self stored in it. He is exposed in one short moment to the nightmare that is the galaxy in M41, all the horrors that took place between the present day and then, and the ten thousand years of unending agony that he experienced. And the bombastic, hammy, literally larger-than-life Conan, Emperor of Mankind, is reduced to a quiet (for him) "I see." His next action is to completely break character and wrap Roboute in a tight hug in the middle of a battlefield and in front of both of their armies, and it's doubtful that this is just for his son's sake as part of Conan's deliberate arc to be a better father this time around.
