  • -1539 DR to -1502 DR

  • -1525 DR

  • Merrow and koalinth band together into the Horde of Bloodtide, only to be defeated again by the mad King Kyron of Thalorlyn. The rebel Republic of Tivaan rises among the merfolk to unite the Hmur Plateau against Aryselmalyr's mad ruler, once spies reveal that Coronal Essyl and King Kyron have allied with kraken to supplement their power. »

  • The Fourth Seros War

  • -1399 DR to -1396 DR
    The Hmur Plateau becomes overrun by a horde of koalinth and merrow, ending the peaceful merfolk Republic of Tivaan. A desperate mermaid steals the Emerald Eye of Kyron from the Dukars' Tower at Myth Nantar to drive the horde off the plateau, only to become corrupted by its power and lead the horde herself against her remaining people and the rest of Seros. »

  • -1396 DR

  • End of the Fourth Seros War
    This war destroys the Second Kingdom of Kyron, setting back koalinth population for decades. The Emerald Eye is recaptured, and the possessed mermaid is believed dead, buried in a collapsed reef on the Plains of Duna, which hereafter are called the Haunted Plains. The new merfolk community, under the auspices of the kindly Coronal Vaequiis, is the kingdom of Thalvan, led by King Darmox. »

  • -240 DR [Year of Enslaved Swords]

  • End of the Elf Purges
    After fifteen years, the worst of the backlash against the sea elves dies down in Seros. Those who survived the attacks from Koalinth, merfolk, and locathah zealots, and the newly returned (and far more evil) morkoth do so by use of magic (including High Magic) and some Dukar protection. »

  • 771 DR [Year of the Stalking Knight]

  • The depths of the Dragonmere off Cormyr become the home to the sea elf kingdom of Naramyr, a former barony of Aryselmalyr. Sea elves resettle here after being refused to form colonies on the Hmur Plateau by Eadraal. Their best protection is the Haunted Plains, which keeps all but koalinth and other monsters from their borders. Alliacnes with Keryvyr also help. »

  • 1369 DR [Year of the Gauntlet]

  • Flamerule 16 Disturbances at Coryselmal draw little attention, though many report hearing sounds of unleashed power from the ruins followed by deep laughter echoing along the currents. Koalinth activity picks up during and after this time. »

  • Eleasis 4 Vhaemas the Bastard and the merfolk of Thuridru ally with Iakhovas and the Sea Hulks koalinth tribe to help decimate the southern Xedran Reefs, which are starting to react to the presence of the sahuagin. »

  • Marpenoth 9 Iakhovas uses magic to summon some monstrous elder form of kelpie all around the Whamite Isles, drawing its entier population into the sea to drown and rise as sea zombies. Iakhovas' army of drowned ones (as sea zombies are referred to), lacedons, koalinth, and merfolk traitors marches on Voalidru and the Lower Hmur Plateau.
    This even lasts until Marpenoth 13, 1369 DR. »

  • Marpenoth 19 Fall of Avina, Lacuan, and the abandonment of Voalidru to Iakhovas and his invading army. Naulys doesn't fall due to the rescue by revenge-driven 'chitls from the Xedran Reefs killing 75% of the koalinth forces.
    This event lasts until Marpenoth 25, 1369 DR »

  • 1370 DR [Year of the Tankard]

  • Eleasis Direct trade opens between Cormyr, Myth Nantar, Naramyr, and Eadraal as the surface-worlders send down sculptures and pickled fruits, while the sea folk send up raw coral, gold bars, and other items lost to the sea bottom.

    The merchants of Westgate quickly realize that the long-standing presence of koalinth tribes in the waters offshore put their city at a severe trading disadvantage in comparison with Starmantle. »
