Ancient Empires of Altanis - Boundaries
Empire of Nerath (ca 3700-4200 BCCC): Founded by exiled Alryan nobles from the City State of the Invincible Overlord. Northern boundary at the River Greyrush & Lake of Temple Deeps, abutting Tharbrian, City State and Skandik territories. Extending south over the Ghinarian hills, beyond the Lake of Visions into northern Arkhosia/Oricha.
Bael Turathi ‘Empire of Glorious Doomfire’ (ca 1500-2500 BCCC)– founded by Ghinoran colonists who interbred with the indigenous Altani, eventually carving out a powerful sorcerous state from the decaying empire of Kelnore. Interbred with demons to create the Demonbrood/Tieflings. Battleplain Gwalion (Viridistan/Tharbrians) in the NW, Plain of Cairns and Sea Rune (Amazons) in the NE. South to the Ghinarian Hills and the dismal swamps SW of the Castellan Mountains, abutting the territories of Arkhosia. Destroyed in war with Arkhosia by the backlash from the Rain of Colourless Fire which annihilated Bael Turath, then by subsequent Altanian slave uprising.
Dragonborn Empire of Arkhosia (ca 1000-2500 BCCC) – Founded by the Dragonborn, a race created as slave warriors by the Orichalan Dragon Lords. From the southern borders of the Turathi Doomfire Empire, south across Oricha and Isle of the Blest, with outpost colonies in Ghinor beyond the southern sea. Capital Arkhosia in northern Isle of the Blest and other cities along the Straits of Oricha were destroyed by the Turathi Doomfire, eliminating Arkhosia in a single blow.
Empire of Kelnore (ca 500-1500 BCCC) – Founded by Northmen who copied and adapted Ghinoran culture. Extent as described in WoHF, across all Altanis/Pazidan and far to the NE.
Ghinoran Successor States (ca -500 to +300 BCCC) - arose in the aftermath of the destruction of the Orichalan Dragon Lords. Ghinoran city-states spread across Ghinor, Oricha, and the Ghinarian Hills, with outposts far to the north and west.
Empire of the Orichalan Dragon Lords (-2927 to -575 BCCC) – The only major power to survive the War of the Pious and Philosophers which destroyed the power of science across the Wilderlands. The Dragon Lords were humanoid entitities who bound the power of the mighty Dragon Kings to their will. At its height, the empire extended across all Pazidan, the Antillian Peninsula, and beyond, far into Ghinor to the south, and north across the Winedark Sea. Following a disastrous century-long war with the Demon Empires of the far south, Orichala was destroyed by a combined slave uprising of the Altani tribes under Bondorr (now god of swords), the Dragonborn slave warriors, and to the south the proto-Ghinorans under Prince Ghinor.
Altan Federation(ca -4000? to -2391 BCCC) - This almost unknown technological and peaceful culture predated the rise of the Dragon Lords, and was destroyed by them before and during the War of the Pious and the Philosophers. Originators of the Warforged. There are indications that the Altan in their desperation may have allied with the alien Markab. Probably was roughly coterminous with modern Altanian territories in Pazidan, north to the Roglaras/City State territories.
