The Story of Ornn
Ornn is one of the Freljord's ancient demigods — the Ram, the Fire Below the Mountain, the divine craftsman who taught mortals metalworking in an age so distant that the teaching has become legend and the legend has become religion. He forged weapons and tools for mortals and for gods, working alone beneath a volcano that he has made his permanent home, and when the work was done and his siblings — the other Freljordian demigods — grew loud and demanding and political, he withdrew entirely.
He wants to be left alone. This is his primary and most consistent desire: to work at the forge, to craft things that are real and solid and not subject to the complications of divine politics or mortal worship. He has been disappointed in this desire consistently because his siblings are not inclined to leave him alone and the mortals who know his legend have a habit of coming to his mountain with requests. He responds to both with the specific grumpiness of someone who has made peace with solitude and keeps having it interrupted.
He can forge items from the living rock — working without fire, shaping materials at a molecular level through the demigod's power that is native to him — and the things he makes are genuinely extraordinary. He does not advertise this. People find out anyway and come to the mountain and he makes the thing because refusing takes more energy than just doing it. He is not kind. He is reliable, which is better.
