Having done some inside work, Section Unicorn decides that the best plan is to go in at night, and collectively goes to scout as night approaches so they will know how to do it when they really want to. Unfortunately, Sasha finds a great hiding place to observe things... with a big Havonian already in it. He doesn't see her, but as she watches him he heads into the building during a break in the guard pattern.
Knowing this, the previous plan gets advanced - clearly they need to get to the wine before he does. Sasha in the lead with her arcanological grappling hook, they ascend to the roof and make their way across it. At the rose-colored skylight, Ivar heaves it out only to discover that there is nowhere to put the skylight on the roof without it sliding down and crashing. So he holds it and after Sasha and Gaius descend into the gallery he starts lowering the skylight after them on the rope.
Unfortunately Malagi (it is in fact Malagi) also enters the gallery, through a hatch in the floor. He immediately announces his intentions - "I regret I'm going to have to kill you" - and attacks Gaius, who can barely defend himself from the powerful warrior's claymore with his rapier. Then Ivar drops the skylight on him.
This knocks him down and sticks some glass in him, but he's not stopped. Sasha runs and hides, Ivar jumps from the skylight at Malagi but is nearly impaled on the sword and has to abort to an unpleasant landing. The guards from the hall enter, and Baba starts lowering the running music box down into the fray. Then she lays the guilt on Malagi, who clearly doesn't want to kill them - and together with Ivar reminds him of a famous Havonian warrior who rather than do something he didn't wish to do was able to die with honor by doing it too enthusiastically.
Malagi then charges the two Pennisian guards with a crazed maneuver that against a warrior of his caliber would be an amazing move. Against these guys, it's suicide, because they don't react right, and Malagi is impaled on their swords. Then the music box of sleep finishes its verse, putting everyone in the room (Sasha having run out in the nick of time, after finding the wine bottles) but Ivar and Malagi to sleep.
Ivar is about to kill Malagi when the Havonian offers that the special prisoner, after forcing Malagi to break him out, headed back to the Elven lands while sending Malagi to interfere with the Group on the theory that Elven plots should be defended rather than from specific knowledge. Thus unburdened, he lets Ivar take his head off.
Section Unicorn then destroys the 24 bottles of Generaux special reserve and retreats, leaving the incendiary device behind them to burn any evidence and the rest of the really good wine. Back at camp they find that Buntrian has readied the wagon, and they flee into the night and back to the capital.
