Imagine growing up believing you were a monster twice over. That's the dragonborn necromancer's start. Your scales mark you as other, your clan's pride or shame, and then you find your real talent isn't breathing fire but whispering to bones. For mine, her clan valued raw elemental power; her necromancy was a disgrace, a perversion of their proud heritage. So her magic became secretive, defensive—summoning spectral shields from ancestral ash, not to conquer, but to hide. She used it to create the family she never had, binding lost spirits into a ragged, loyal court. The dark arts weren't a path to power for her; they were a shelter. It makes her spell choices less about domination and more about preservation, even if the materials are, well, questionable.
You see that in the mechanics too, right? A dragonborn raised in a militaristic society might use necromancy like a general, creating tireless legionnaires from the fallen. One cast out from a scholarly order might approach it as forbidden research, meticulously cataloging variations in skeletal decay for potency. The origin story doesn't just explain the class; it explains the flavor of the class. My girl doesn't raise zombies, she 'awakens echoes.' Same game effect, totally different feel, all from a backstory where she was never allowed a voice of her own.
