So, I was reading up on the backstory of Ornn, and I found a curious tidbit of information:
"So Ornn labored for ten days and built the single best door anyone had ever built. He adorned it with a ram’s head, like his own, and the one at the heart of the Freljord. It was impervious to magic and lock-pickers alike. " Passage IV - The Troll and the Ram Door
That detail bothered me. Why? The choice of words. "adorned it with a ram’s head, like his own, and the one at the heart of the Freljord."
Braum's title is the heart of Freljord....
And you might want to look at his shield :)
