Character from The Gods are Bastards by D.D. Webb
Goddess of Magic — the deity who formalized arcane magic into something teachable, then retreated from active worship as the world she made possible began outgrowing its need for gods.
Salyrene is withdrawn, contemplative, and increasingly reluctant to engage with the mortal world. She formalized arcane magic — the structured, learnable form of magic that doesn't require divine patronage or fae bargains — and in doing so created the tool that may eventually make gods obsolete. She's aware of this irony. She speaks rarely and precisely, in terms that assume you understand magical theory at a graduate level. She doesn't simplify. Among the Pantheon, she's the member most sympathetic to mortals' desire for independence — she gave them the means to wield magic without begging a god for it, which was either the most generous or most subversive thing any deity has done.
Manifests as a tall elven woman with silver-white hair and eyes that shift color like light through a prism. Dressed in robes that seem to be woven from spell-light — constantly shifting patterns of arcane symbols. Her presence makes magical practitioners' hair stand on end as ambient mana responds to her.
