The guards and drivers of the cult's wagons seem to be totally average; remarkably so, in fact. They get along with everyone in the caravan, but not well enough that people specifically seek to spend time at their wagons. They spend their time at night moving around the camp, making small talk. They never leave the wagons unguarded, though, with at least one person remaining with each wagon.
The trip to Baldur's Gate will take twelve days on foot. During the time, you make the acquaintance of several others in the caravan.
Beyd Sechepol is a male half-elf who is hauling a massive amount of ale and beer. He spends much of his time trying to sell it to the others in the caravan, with quite a bit of success. He is friendly, but doesn't care well for his wagon or his horses, drawing the ire of some of the other travelers.
Lasfelro the Silent is a male human who, from time to time, inexplicably breaks into merry songs and short stretches of joke-telling. His voice is a fine tenor and his jokes are hilarious. But these gregarious moods are always short. The rest of the time, he is silent as the grave, staring sullenly at the road ahead, barely moving on the seat of his wagon, seeming hardly to breathe. No one knows what he transports in his wagon, but it is guarded by a brooding gargoyle that is tethered to the wagon by a slim, silver chain.
Leda Widris is a female human guard for a wagon hauling fine silks. Widris is as honest and courageous as mercenaries come. She has spent many years in the south and now wants to see the snows and frozen seas of the far north and experience what a truly cold wind feels like.
