The islands south of Faroth start with Belgar island. Belgar is populated with sea elves, and they trade mostly with the eastern shore, the Burati valley. Burati is populated with elves and humans, bounded on the north by Burati mountains and to the south by the Burati river. The mountains are enough of an obstacle that overland trading is uncommon at best.
On the south side of the Burati river, is the kingdom of Kyln. Kyln is ruled by hobgoblins who have an amicable peace with the elves to the north and an active defense to the west against the Ogres of the Whitechalk cliffs. This far south, the southern end of the Sing’jar mountains curves west and ends as the Yil range, holding the Yil valley. Kenku and hobgoblins freely mix, under the rule of the Kyln kingdom.
The Whitechalk cliffs are a giant slope from north to south, with giant chalk cliffs on the south side facing Danclar bay. Not only do communities of ogres protect the peninsula, other accursed beasts and undead inhabit the chapparal of the region. Deep canyons hide communities of lycanthropes and rumors of dinosaurs have been heard, too.
At the western tip of the cliffs, the Danclar islands are a dangerous place for sailors to stop: Yuan-ti have occupied these islands once peacefully occupied by lizardfold sahaugin. Trade is sanctioned in official marketplaces and tourists are arrested and deported if they are caught away from the marketplaces. There are no inns on the Danclar islands. Any ship sailing south is obligated to pay for permits for access to the south. The Yuan-ti navy patrols the islands.
If a crafty trader sails south east of the Danclars, heading into Danclar bay is frought with challenges that often take rituals and sacrifices to avoid. Elasomosaur, chaotic aquitic elves and merfolk populate the bay. Sirens camp on the rocky shores beneath the chalk cliffs. Navigating to the Yil valley, you would meet the last free lizardfolk and kua-toa, that are ostensably policed by the yuan-ti Yaan’bu empire. Since the lizardfolk are unable to escape, they are the only effective kelp farming and fisherman for the Danyil bluffs region, and given some latitude of freedom.
Yuan-ti bougeoise live above the Yil valley in the rocky bluffs in the Danyil bluffs. These snake peope own the trading companies that operate out of Dardan City, in the bay to the southeast of the bluffs. Dardan city is the heart of commerce, with a healthy population protected from the dinosaurs and other sea monsters to the northwest.
Off the west shore of Danyil bluffs is Egza island, the largest prison island of the yuan-ti. Egza island used to be the prison island of the previous despots: the Naga nation of Bundash. Egza island is now a prison for the remainder of the Bundash naga. The waters around Egza are policed by sahaugin and other aquatic races allied with the yuan-ti.
The other island on the south side of Dardan bay is Fylwen island, another yuan-ti prison. Fylwen is the ancestral home of the region’s minotaur. Six hundred years ago, Sing’jar straight saw a fleet of minotaur refugees travelling north. This was the wave of refugees displaced by the Yaan’bu empire. High elves and sea elves were also displaced by this yuan-ti expansion hundreds of years ago.
