Speaking of the initial topic of this thread….
Onyx and Lucian are both biologically male (Onyx is genderfluid though) so they can't have kids. Onyx and Lucian both wanted a child, however,as Lucian, being the foolish human boi in the scenario, dabbled in dark magic to make them a son. However, dark magic is obviously a bad thing and despite the fact that they had a son, he was also destined to kill both his parents on his nineteenth birthday. Onyx disapproved of Lucian's methods but, not knowing about the prophecy, came to care for their son very deeply and emotionally, but Lucian was filled with unease. Onyx came home the night before their son's nineteenth birthday to find Lucian holding their son's still-beating heart in his hands and covered in blood. Lucian ripped his son's heart out of his chest just to save Onyx because he couldn't bear to think of a world without his partner, and now their son is dead and Onyx hates Lucian forever. They both end up committing suicide.
If that's too goddamn sensitive for you guys, deal with it okay? I'm a salty bitch. But while I haven't experienced homicide myself (thank god, I don't really have interest in murder but it's still a good thing) I have experienced death of someone very close to me, broken relationships, and suicidal ideations so fear not, I do know what the fuck I'm talking about!
