[Mortus casts Aura of Protection. -4MP]
Sybo nods, and casts the spell [casts Mystic Mist]. A cloud of mist rises up from the water and spreads across the southern half of the warehouse. He gestures, causing it to spread out still further. Now it's thick enough to provide concealment, but not so thick that it's impossible to see where you're going.
Hans and Admund advance to the warehouse under the mist cover. The others stay back. The ground underfoot is covered with gravel, but the mist muffles the sound. Hans begins to climb the stone wall, while Admund moves around to the south-eastern corner. The building consists of two, double-storied storage areas, with a linking section (single-storied) between that probably contains offices. Each storage area has a set of double doors at the front at ground level. Above, another set of double doors opens into the air - above them is fixed a pulley to allow goods to be lifted directly to the upper level from outside. All the doors are closed.
Hans [scale sheer surface] easily climbs the rough stones of the building's lower level. He pulls himself up further, holding onto the timbers. Now he's reached the window. The shutters are held in place by an internal bar (this could be forced open, but not easily). But he can see through the gap between them. He's looking into a large storage room, mostly filled with crates. A set of stairs by the western wall lead down. The only other exit is the loading doors, and leaving that way would mean a substantial drop. There's no one in this room. However, he can hear muffled voices from the stairway - there are people in the ground-level storeroom. A moment later he hears the crack of a whip.
Admund peers around the front of the building. He can see as far as the land side of the jetty, though only indistinctly because of the mist. But he hears a door open, and a moment later sees someone walking from the middle part of the building towards the jetty, carrying a pair of lanterns. It's a short, spindly man with stooped shoulders and long hair. He's muttering something to himself, but Admund can't make out any words. He continues towards the jetty, perhaps intending to set the lanterns at the end to guide in boats.
As he's watching this, Admund [acute hearing] becomes aware of muffled voices through the double doors of the warehouse. Then [at the same time as Hans] he hears the crack of a whip.
