Sons of the Citadel
Although considered a kingdom or an empire by most outsiders, the Rhoynar consider themselves more an alliance of free cities all bound to the Mother Rhoyne, as they call the great river. The various great cities of the Rhoynar are all built alongside the Mother, and most of their livelihood comes from her. The Rhoynar are generally a peacable people, but that peace has come through strength.
The secret of forging iron came first from the Rhoynar, and they used the power of their iron spears and swords to make it quite clear to their neighbors that their borders were their own. The brutal defeats suffered by early attempts to invade Rhoynish cities and territories have been enough to keep such incursions from happening for centuries, and only a fool would attempt to assail a Rhoynish stronghold on the shores of the Mother itself, where their water witches are at the height of their power.
Like most river-founded civilizations, the Rhoynar prosper through trade and fishing primarily. Down the Rhoyne come goods from Andalos, Qohor, and even the Kingdom of Sarnor at times. From the mouth of the Rhoyne at Volantis, these goods then find their way to the Valyrian Freehold, Ghis, and even ports as far-flung as the Summer Islands, Lys, and Tyrosh. And, of course, the trade flows in the opposite direction as well, making Volantis one of the richest trading cities in the known world.
