  • 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. »

  • 1385 DR [Year of Blue Fire]
  • Yaphyll, zulkir of divination is taken prisoner by Szass Tam, binding her with the Death moon orb and Thakorsil's Seat, powerful items of domination. He forced Yaphyll to perform the most powerful divination known to her order no matter the consequences to her own well-being, and to tell him how to arrange for a decisive victory over the other zulkirs. She performs the task and tells Szass to lay a trap at the Keep of Sorrows. Then she leaves him with another vision:

    The white queen is troubled but can't say why. The black queen hates the white and gives the assassin a black coat. The assassin steals upon the white queen. She can't see him gliding through the shadows. The sword screams. The white queen falls. Her city falls. Stones fall in the cavern to crush the soothsayer. The tree burns and thrashes in agony. Branches break. Branches twist and grow together..."

    At the end of the vision Yaphyll was surrounded by a blue flame and broke free of Szass Tam's power. The lich killed her with his poisonous touch trying to regain control over the diviner.

    As Yaphyll predicted, the fight at the Keep of Sorrows turns into Szass Tam's favor. With the help of the Death Moon Orb, Szass tries to coerce his former ally Dmitra Flass, into fighting for his side. But then the Spellplague hits. The Death Moon Orb explodes in Szass Tam's hand, freeing Dmitra of it's power. Szass is hit by a wave of azure fire, a result of the Spellplague, rendering his magic close to useless and burning the flesh from his face and hands. The lich flees from the scene by the help of Xingax.

    By revealing to Malark Springhill why he killed Druxus Rhym, the lich convinces the spymaster to switch sides and work for him and his greater cause henceforth.

    In order to learn more about the ways of magic in the time of the spellplague Tam summons Bane, sacrificing the tharchion Pyras Autorian in the ritual. Bane makes a bargain with the lich and grants him great power. Szass in turn surrenders his soul after 1000 years had passed when his quest of conquering Thay was completed.

    Szass summons a dream vestige to turn the tide in his favor. He succeeds in beating the legions of the zulkirs, chasing them all the way to Bezantur. His undead legions and loyal priests of Bane further force the zulkirs to leave the town aboard vessels. Szass summons the bodies of drowned men and also undead aquatic beasts for a final and lethal victory over the zulkirs. Accompanied by a fleet of warships made from darkness, Szass follows the fleeing zulkirs, entangling them in a marine war. His enemies and the zulkir Nevron's conjured denizens of the infernal oceans proved quite adept at sea fight, beating back his undead minions. Szass conjurs the dream vestige again, finally exhausting his magical powers bestowed by Bane. When Bareris defeated the dream vestige and the zulkir's forces beat Szass Tam's minions, the lich and Malark withdrew to the Thaymount, the lich being content with his conquered lands. Szass didn't bother chasing the remaining zulkirs any more, leaving Aloar and the Wizard's Reach to them not fearing any retribution by the depleted zulkir's forces. He reveals to Malark, that he found a book once in possession of Fastrin the Delver. »
