The party was summoned by Elka, a deva coordinator in Haven, to investigate reports of trespassing on the Island of Lost Souls. They discovered that the Mazer Corps was breaking into the ruins of Stronghold. The Mazer Corps was hired by the Maedo Group, a tiefling criminal organization. The dig was ordered by Silver, a flamboyant elf who hired the party (in “adventurer” disguise) to investigate Stronghold and bring back or destroy anything non-Eladrin.
Using the Amiasmic Censer, the party descended through the necrotic Miasma of Stronghold. They found Corbuzzash, a devil scholar, studying the Miasma pouring out of a large cube with a keyhole. He provided them access to an oracle that gave a strange prophecy. Following the chain from the cube, they eventually found their way to a dig site. On the way, they had a vision of the origins of the Eladrin Plague.
Judas had invited a group of Ioun/Vecna researcher cultists to witness the opening of an obelisk. Inside was a cube covered in chains that shot out three locks and the Miasma that destroyed Stronghold. After defeating Andraste, one of the researchers, in Efrat’s body, the party managed to gain access to the dig site.
There, they found Judas covered in spirals and undead. He claimed that they were too weak to stop him, and that the only way to stop the entity imprisoned in the seal from escaping was to let Andraste possess Judas and escape. The party allowed her to do so, and she escaped into the Feywild.
Upon returning to Haven, the Illithid Synapse merchant fleet had advanced on the city. The party was sent to smooth things over diplomatically with Orrhi the merchant queen, but discussions were cut short by the attack of a mysterious Stiletto ship. Rhuu, the three-tentacled collar-maker, recruited the party to help stop it.
The party boarded the ship, and discovered that it was crewed entirely by constructs who were stealing from the Synapse Fleet to gain residuum. The party destroyed the large pilot-construct and managed to crash-land the ship in water. They recovered the pilot’s memory-plates and the ship’s lift core.
Now, on the advice of Silver, the party has arrived on the volcanic island of Hyperion to consult with the oracle there.
