• The Second Epoch of Seros
  • -14000 DR to -215 DR
    Time of the elves in Seros (the Inner Sea). The Second Epoch officially begins with the building of the undersea capital of Aryselmalyr, and ends with forty years of war between the sea elves and other undersea races. It is also during this Epoch that the first land dwellers began exploration of the waters (wizards of Netheril), the initial migration of shalarin into the Inner Sea, and the trapping of the sahuagin behind the Sharksbane Wall. »

  • -11743 DR
  • Establishment of Coryselmal, the Coral City, capital of Aryselmalyr in Seros. »

  • -11400 DR
  • With the start of the Sable Wars and the fall of Eiellur (coupled with the Crown Wars), a sudden influx of elves entering the Inner Sea forcing the elves out into deeper seas and away from the coastal waters. This ignites the first major conflicts with merfolk and sahuagin. »

  • -11200 DR
  • With another major migration of elves to the Sea of Fallen Stars after the fall of Thearnytaar, the sea elves expand militarily beyond the Selmal Basin and establish the kingdoms and regions of Coranthys, Tor Meraliir, Ullythan Reef, and Ryeniir. »

  • -11003 DR
  • Rise of the Aryselmalyr Empire
    Coryselmal, the grandest of the sea elf cities of Selmyr (an elven kingdom of the Selmal Basin), becomes the capital of the Aryselmalyr Empire over all the elf kingdoms of the Inner Sea.

    The Aryselmalyr calendar marks Year 1. »

  • -9872 DR
  • Sea Elven garrison towers built among the Sharksteeth Mountains (the mountain range where the current Sharksbane Wall), with the help of Vodos the Great Builder. »

  • -9845 DR
  • Construction begins on the Sharksbane Wall (uniting the existing tower garrisons) designed as a barrier against the sahuagin incursions, stretching between the Akanapeaks of northern Chessenta and southwesternmost Altumbel, southwest of Delthuntle by clergy of Deep Sashelas, Trishina, and Eadro. »

  • The First Seros War
  • -9839 DR to -9833 DR
    The burgeoning empire of elves allies with the merfolk against the sahuagin of eastern Seros. »

  • -9833 DR
  • End of the First Seros War
    This war destroys the major sahuagin kingdom in "Sekolah's Trench" (the Trench of Lopok). Wars and skirmishes continue across centuries to slow or stop the building of the Sharksbane Wall. »

  • -9000 DR
  • End of the Fifth Crown War
    The Fifth Crown War ends with the utter defeat of the Vyshaan and the dissolution of Aryvandaar. Much of the High Forest is abandoned for an age, leaving the forest open so the gods might restore its peace. Many elves begin migrating back to the Elven Court in the eastern forests, while others migrate into the Inner Sea (this marks the last great elven migration to Seros). Keltormir and Illefarn emerge intact from the Crown Wars, and the latter realm joins with the vassal realm of Ardeep now that Shantel Othreir is no more. »

  • -8938 DR
  • The 135-mile-long Sharksbane Wall is completed in Seros, effectively imprisoning the sahuagin in the southern arm of the Inner Sea (strong armies can overwhelm defending forces and storm over the wall, but no raiders can slip through casually or unnoticed). Over the nine centuries that follow, sea devils west of the Wall are ruthlessly hunted down and exterminated. »

  • -8830 DR
  • In Seros, the five Tunnels of Iratis are completed by the end of this year. »

  • The Second Seros War
  • -8298 DR to -8282 DR
    The elf empire uses locathah forces to rally the enemies' enslaved locathah against them, as well as merfolk and crabmen. »

  • -8282 DR
  • End of the Second Seros War
    This war destorys the Kuo-Toan Consortiums. All their cavern cities along the Plains of Duna collapse, and their people are put to the slaughter, rendering the kuo-toans nearly extinct in the Inner Sea until the present day. »

  • -8000 DR
  • All sahuagin settlements in the Inner Sea (Seros) lying west of the Sharksbane Wall are destroyed by this time. »

  • c. -7700 DR
  • Rise of the Marid States
    Rogue marids from the Calim Empire enter Selmalyr (undersea Vilhon Reach), sparking war with the sea elves. Within a year, the marids and their jann spread into Seros, allying and sharing their power with the other aquatic races. Because these new Marid States are located in deep water beneath the Hmur Plateau, their residents face no direct retribution from the elves for their expansionist activities. »

  • -6946 DR
  • The Mervae Alliance
    Dukars develop their powers and become peacekeepers across Seros in alliance with Aryselmalyr. Unlike other forces, they are not required to make oaths of fealty to the sea elf empire. »

  • -6681 DR
  • The four academy cities of the Dukars are all completed this year in Seros. »

  • -6676 DR
  • The Golden Era of Aryselmalyr Begins
    With the end of koalinth border wars against the elven cities of the Hmur Plateau and the Selmal Basin, and a peace accord with the Marid States (as some jann join the Dukar Orders), this marks the beginning of 5,000 years of general peace in Seros. »

  • -6100 DR
  • End of the Marid States
    The deep-water Marid States mysteriously vanish or fall prey to kraken attacks. Many marids and jann also vanish or die over the course of sixteen years, though the bulk of the disappearances occur this year. This ends the major challenge to Aryselmalyr's control of Seros, thought the Dukars temper their rule. »

  • c. -1720 DR
  • The Netherese begin to explore Seros. They establish three crystal-doomed, subsea colonies - Cuulmath, Werapan, and Quelauuvis - on the continental shelf off the land that will become Sembia (over the Plains of Duna), which is within claimed territories of the elves and merfolk. Netherese mages either keep Aryselmalyn forces at bay or enslave any Serosians that enter their sphere of influence. The colonies are collectively called Deep Netheril. »
