Lands of Mystery
Most of these geographically isolated areas were settled centuries ago by Suloise peoples fleeing the Oeridians, though the Sea Barons exhibit Oeridian and Flan influence as well.
Tilvanot Peninsula — Separated from the southeastern Flanaess by rough hills and the Vast Swamp, the Tilvanot Peninsula is dominated by a plateau about sixty miles wide by two hundred and forty miles long and is home to the mysterious Scarlet Brotherhood.
Asperdi-Duxchan Islands — Numerous islands and a minor continent lie off the eastern and southeastern coasts of the Flanaess. The Asperdi-Duxchan island chain includes the four major islands of the piratical Sea Barons, the Lordship of the Isles and the Spindrift Isles (also called the Lendore Isles). As they near the ends of their long lives, aging elves across the Flanaess are drawn to travel to these islands, but what happens there, no mortal can say.
Hepmonaland — Only a few dozen miles across the Tilva Strait from the Tilvanot Peninsula is the minor continent of Hepmonaland. Hepmonaland is almost entirely unexplored, a tropical region where rain forests cloak the land.
Amedio Jungle — A second tropical region lies to the west of Hepmonaland, across the pirate- and monster-infested Densac Gulf. The Amedio Jungle's northernmost part reaches into the Azure Sea. Here, pirates and slavers from the Hold of the Sea Princes raid or trade with the jungle residents. Ancient ruins and savage monsters fill the Amedio, which is cut off from the rest of the world by the Azure Sea and Densac Gulf and by the volcanic Hellfurnace mountains to the west.
Sea of Dust — The Sea of Dust lies to the southwest of the Flanaess, across the Hellfurnaces from the Amedio Jungle. This ash desert is all that remains of the old Suloise Empire, also called the Suel Imperium, after the Rain of Colorless Fire about a thousand years ago. Portions of the Sea of Dust are navigable using special boats. This region is extremely hostile to humans, but a strange ecology has developed, with rock-eating creatures, giant slugs, burrowing beasts and other monsters.
Under-Oerth — Beneath the Hellfurnaces and parts of the Crystalmists are huge tunnels and caverns that stretch underground for perhaps thousands of miles. Only a fraction of this subterranean realm has been explored by humans, who generally avoid the evil races that live here. This realm is called by some Under-Oerth. Its best-known feature is the gigantic city-cavern called the Vault of the Drow, though a great underground river and sea are rumored to exist as well.
