An agent of Daask, a half-orc named Gran, approached the Railjacks at their hideout, with a job offer. Daask was moving in to the Ambassador Towers district, which was currently run by the Tyrants, a gang of Changeling information brokers and spies. The job was to assassinate one of the Tyrants' informants, Ushrir of Clan Toldarath, who works at the Mror consulate.
The group managed to sneak in with a cover of negotiating a trade agreement with the Lhaazar Principalities, but still needed to sneak their way into the Toldarath enclave within the embassy.
They caused a distraction in the inner chambers of the enclave, where Ushrir was eating, and snuck him out invisibly. It seemed, however, that someone knew that he had been taken; there was a heavily armored guard stationed at the door to the embassy tower, preventing the group from exiting without a fight. The Railjacks also heard an additional voice where Ushrir's invisible form was positioned.
The party made short work of the guards, who all seemed to be changelings in dwarven disguise. Finally, the unseen voice revealed themselves. A changeling form appeared before them and offered to talk things out. They appeared unfazed, and a little annoyed, by attempts by the party to wound them, but retreated before they could suffer any real harm. They said to spare Ushrir's life, and then the Tyrants would work with the Railjacks to counter Daask influence throughout the city.
The Railjacks decided to remain professional and honor their contract by not immediately siding with the Tyrant, but neither did they kill the dwarf. They flew off in their skycoach with Ushrir in tow.
