Suuheshbi
Called Suuheshbi by Dragonborn and Dwarves, their name has been distilled down to Sudehsi in the human pantheon
the First God
Large enough to swallow the continents
Heavy
A giant dragon with nonreflective black scales
most closely associated with fire and life
A dragon skull, bleached white, or as a white fang on a red background
The Dwarves, first to emerge from the depths of the earth and conquer their neighbours, say the world was brought to be when dragonfire from the First God scorched the great black waters and exposed the rich soil beneath it.
The Dragonborn, who claim descent from Suuheshbi and their kin, say the great God was born of a massive egg, incubated in the waters and silt, and set the world alight at their loneliness. From the mud and silt, they shaped companions - including the form of a dragon such as they - and breathed life into them.
