  • Evidence from the carvings in some sea caves suggests that the merfolk, locathah, and sahuagin exist in Seros and have battled each other since that time. »

  • 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. »

  • -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. »

  • -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. »

  • -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. »

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

  • c. -2300 DR
  • Early boats sail the surface of the Inner Sea around the southern Alamber. Easily attacked and sunk by sahuagin, these boats are small and usable only for coastal fishing, not exploration. Raurinese refugees continue their expansions overland. »

  • -1094 DR
  • Coronal Merath Merynth dies fighting sahuagin raiders, and his wizard son Lynsal becomes coronal of Seros. »

  • -238 DR [Year of Fortunes Fair]
  • Start of the Second Dukars' War
    After seventeen years of constant skirmishes amid all the powers of the central sea of Seros (and a resurgence of the sahuagin presence due to lack of order at the Pillars of the Trident), the Orders of Jhimari and Numos took proactive steps toward maintaining the peace by attempting to found a Dukars kingdom centered on Myth Nantar, Nantarum. »

  • 3 DR [Year of the Faded Flower]
  • Rise of the sahuagin empire of Aleaxtis. The sea devils emerge from a century of war with the merrow of the Alamber to claim more than half of that sea as their own. »

  • 656 DR [Year of Peaceful Seas]
  • End of the Ninth Seros War
    Due to merrow invading their territory and adding to their enemies' populations, sahuagin send massive raiding parties storming over the Sharksbane Wall. All this serves as retribution for the other races invading Aleaxtis, and that continues the Ninth Seros War for another year. »

  • 720 DR [Year of the Dawn Rose]
  • With the Dukars absent, sahuagin raiding parties slaughter the remaining sea elf and merfolk guardians and look to destroy as much of Myth Nantar as possible, though they soon abandon the city due to the uncomfortable nature (for them) of the cities mythal. »

  • 800 DR [Year of the Black Fist]
  • Mysteriously, the shields around the Academy of the Dukars expand slowly over the years since Myth Nantar's fall to sahuagin. Now, all areas where the mythal touches are made impenetrable by all matter and magic save corals, sea stars, and fish. For the next 500 years, folk will swim near Myth Nantar less and less frequently, given the haunting singing that seems to emanate from the mythal when touched. Folklore arises noting that the city is cursed, as are the Dukars, until they perform some penance for all the races of Seros. »

  • 1018 DR [Year of the Dracorage]
  • King Tchazzar of Chessenta (actually a red dragon in human guise) disappears while fighting the sahuagin of the Alamber Sea. His people believe him ascended to godhood, since his body is not found.
    This event begins Tchazzars ascendence to divinity. »

  • 1269 DR [Year of the Moat]
  • The ambush of a hunting party by sahuagin devastates Eadraal as the beloved merfolk Prince Aldem and Prince Consort Kran die to protect Kosul, the king's heir. »

  • 1358 DR [Year of Shadows]
  • The Summer Storm Wars claims many sahuagin lives of the Alamber as well as over thirty ships and 2,000 people of Mulhorand as the god-kings' forces clash with the sea devils. The visitations of Sekolah, Anhur, and other lesser water powers cause much disruption in Seros. The mythal barrier around Myth Nantar crackles and surges but holds against attempts to break the barrier.

    Umberlee ravages the Pirate Isles of the Inner Sea with hurricanes and storms, destroying more than two-thirds of the pirates' fleet (causing many pirates to stop worshipping her). Appearing also in the Trackless Sea, the Bitch Queen adopts the kraken Slarkrethel as her seraph (Chosen). »

  • Mulhorand launches a fleet of ships to capture the island of Alaor from Thay. More than half their fleet sinks in storms or due to sahuagin attacks, and the mission is a failure. »

  • 1369 DR [Year of the Gauntlet]
  • Flamerule 6 The Ship of the Gods volcano in the Alamber erupts, and priests of Geb in the Golden Forge temple within fail to prevent the eruption but mitigate the damage to Mulhorand by venting lava across the sea bed. This causes a tidal wave that swamps the Alaor and Bezantur. Mulhorand briefly seizes the Alaor.

    Soon after the Ship of the Gods erupts, a great subsea explosion shakes rooftops in Airspur and Delthuntle, and the resulting waves cause some damage to their ports.

    The volcano south of Aleaxtis rumbles and erupts, though aquatic earthquakes open fissures along the floor of the Alamber Sea and allow the volcano to expend much of its force and lava along the sea floor. The magma flow both destroys the capital of Vahaxtyl and more than half of the upper hierarchy of the sahuagin kingdom of Aleaxtis, including the king. »

  • Flamerule 26 The Start of the Twelfth Seros War
    Deepwater War
    The monstrous wereshark Iakhovas (known as the "Threat From the Sea") finds an artifact in Coryselmal and uses it to shatter a large section of the Sharksbane Wall, destroying Akhanmyr and one of the Sea Unicorns guardposts in one explosion. The Xedran Reefs take this as a sign that their religious Time of Tempering has begun. Iakhovas and the sahuagin occupy Coryselmal for a time. »
