Seoni, the iconic sorcerer of Pathfinder.
I’ll note that one thing that bugs me about the Sorcerer class *is* that, despite how fairly early in D&D 3e’s life there was a Dragon article talking about many alternative ways to have innate magic other than being born with it, both D&D itself and Pathfinder after it doubled down on the “magical bloodline” lore and terminology.
My preference is more “wizards have an education, warlocks have a magic sugar daddy, sorcerers have a superhero origin”.


Referring back to my “sorcerers have a superhero origin” proposal elsewhere in this discussion… one of the Dragon suggestions for an alternative source of inherent magical power is being the subject of magical or alchemical experimentation.
In Eberron, since it just came out of a massive war that involved advancements in combat magic and artifice, it’s easy to imagine that type of origin specifically manifesting as “Captain America, but a sorcerer”.
