There was a heaving, brass-plated furnace in her ancestry; a people, as you know, who are unusual but not unlovable.
This oddity popped up in stories of her line. A burnished great-grandfather who spontaneously combusted. An aunt who could light stoves with a touch.
She had little to mark her burning past except, perhaps, hot skin, and a mental warmth (which could be ascribed to other things).
And so, little was thought of it, until she met a man who had some waterspout or lake djinn among his ancestors. They met and lived in steam.
Of course, we know now that furnace is a dominant trait, which explained the searing winds and bright, cloudless days that followed her everywhere.
When she left on a holiday, the rain clouds, indignant at their exclusion, returned. They sulked over the city until she came back, and burned them away.
