The river referenced here is the
Zamoyos, which is roughly equivalent to the Amazon river. It comes from deep within the continent and branches into a huge delta, full of mangrove forests, swamps, and thousands of tiny lakes and rivers. This being Sothoryos, the river is of course filled with piranhas, diseases, rotting plants, quicksand and alligators.
It's likely that the alligators are actually not native to the place, but that they were brought here from elsewhere. In the delta, there was once a city called
Zamettar. It was a decently prosperous Ghiscari colony, back in the day when they had an empire. During the 4th Ghiscari War, Valyria finally conquered the place and either destroyed it or abandoned it some time later. This being ancient history, it's hard to say. What we do know is that the city was abandoned for more then a thousand years already when Nymeria was leading the Rhoynar exodus south. At this time, the Basilisk Isles were a pirate infested hell-hole, instead of a Valyrian colony as they would alter become, and after a disagreement with those nice chaps, the Rhoynar settled in the ruins of Zamettar. They also settled another ruin further up the Zamoyos. However, they were plagued by the wildlife and disease and when the other colony suddenly vanished completely, they abandoned Zamettar and headed towards Dorne.
That other city? That is a lovely place called
Yeen. Nobody knows who built this city or when, though scholars agree that it appears not to be of human make. The evidence for that is that the city is made from huge blocks of stone, too heavy for any man to have ever moved them, and nobody knows what to make of the black, oily stone itself either. Yeah. It's an entire city made out of Bilestone. And
something seems to still live there. Said
something being scary enough that even the wildlife stays the hell away from the place.
So in short: Let us stay the fuck away from the river leading to Aberration City.
