Wix checked his dead drop location; he knew that's where his friends in Daask sent them jobs sometimes. And this time, there was a simple message telling him to visit Gnash'vog'thar in the Cogs. The gnollish bartender told them about a contract, given to Daask by an anonymous client. The contract was to kill a minor noble named Daine ir'Bronwyn, who has taken to hiding in his well-protected home.
The Railjacks cased the joint; it's well-guarded by half a dozen warforged sentries, and there's no back entrance. So they made a plan of luring the mark to a window, and having Exile take him out with a well-placed arrow. Scrip and Echo bribed a delivery person and brought a crate of groceries to the front door, while Exile got in position to shoot, and Wix and Tusk hid around the corner to rush in and support if necessary.
Scrip managed to talk her and Echo's way through the door, then had one of the maids show them to the larder in the basement. With silent precision and brutal efficiency, Echo strangled the young khoravar woman while Scrip covered her mouth. Scrip put on the servant's clothes, and went upstairs. She rushed into the kitchen, grabbing a tray along the way, and brought it to the mark's bedchambers. She told the warforged guarding the upstairs landing that she was bringing food for the master, and left the tray inside Daine's doorway, leaving the door ajar. Then, she walked over to the window at the other end of the hall, and "accidentally" knocked over a fragile stone statuette, causing a great deal of noise and commotion.
Meanwhile, Echo was searching around the basement, and found a hidden door in the wine cellar, which opened to a secret closed vault. Exile found a well-hidden vantage point, well beyond normal bowshot range, to further obscure the assassination.
Roused from his slumber by the crash, Daine stormed out into the hallway, sword and potion-belt in hand, but still clad in his bedclothes. Once he got to the end of the hall, right in front of the window, Exile let loose an arrow. The arrow flew well, crashing through the window and lodging itself deep in the young noble's eye socket. As the window broke, the sharp piercing wail of an alarm begun blaring, rousing the guards on the first floor and in front of the door to come to attention.
The arrow struck true, but did not quite kill their target. Scrip had moments to act before they were discovered, and act she did. Before the warforged could come to their master's aid, she seized the arrow, embedded in the man's eye, and shoved it as deep as she could, riding his fresh corpse to the ground. She begun wailing desperately, making a big show of trying to aid the dead man.
Tusk and Wix used the distraction of the guards heading inside to spring into action as well; they rushed into the door, and right down the stairs towards Echo and the vault. The three of them worked swiftly; Echo did the primary job of opening the locked door, but utilized his compatriots' dexterity and expertise to disable traps and wards as he found them. They opened the vault without any other problems, and saw two small chests of gold and jewels and a bright golden wand with the symbol of Boldrei, goddess of Hearth and Home, at the tip. They emptied the chests into the grocery crate, stuffed the maid's body inside the vault, and closed it all up, leaving no trace behind.
Upstairs, the warforged had assembled around Scrip and Daine to protect them, as Exile rained down volley fire from his unseen hiding spot. The warforged could do little except hide behind their shields. The valenar elf hit one of the potions on the potion belt, causing a showering explosion of frost, which killed two of the guards, and injured Scrip. The half-elf grifter became even more hysterical, attempting to rush downstairs. The warforged tried to stop her, and cover her from the incoming fire, but she pulled the guard's shield down at the exact right moment for one of Exile's arrows to pierce his skull, killing him instantly. She threw him off of her and rushed downstairs.
Waiting for when the door guards' backs were turned, Echo, Tusk, and Wix joined Scrip in rushing towards the door. Since the guards were focused on looking outside, it was trivial for four sneaky assassins to dispatch them quickly, and they ran out the door.
The Watch had not yet shown up, so they seemed to be in the clear. There wasn't much of an indication in the papers the next morning about the murder in Stormhold, so it seemed like they might get away scot-free. Wix's dead-drop had the full payment in it the next time he checked.
