November 13, around the farm
Given the distance between yourselves and the buildings, and the cover provided by the trees, Bendyn and Casparan are able to circle around the farm with a reasonable degree of confidence. For the next ten minutes or so, you see or hear nothing to suggest that you have been noticed. You make it around as far as the small outcrop of trees slightly to the west of north of the hall.
But all that hard work is rather for nothing when you hear shouting and the whinny of paniced ponies (and a horse) from the forest on the other side of the farm. A moment later, the ponies break from the cover of the trees at a canter, heading for the farm. On one of them is a man, crouched low against the pony's neck.
From behind the hall emerges one of the figures from their hiding place. There is a shouted challenge, or perhaps its a warning, and a response from the man on the pony. The ponies cross the stream and into the center of the farm. More figures emerge, probably from the hall but you can't see the door from where you crouch. There is more shouting, and several of the ponies are grabbed. One shys away, heading south, Bendyn's horse by the size of it. The rider slips from his pony and is surrounded by several others. There are probably about four or five figures in the central area now, although from your position, part of the area is obscured by the hall and the figures slip in and out of view. And in the half light of the moon, it's impossible to distinguish individuals, and thus count the number with any accuracy.
ooc: the above events take about 2 minutes to play out. You may use that time as you wish. If you do anything that would draw attention to yourself, I'll adapt the above as appropriate. However, for those two minutes, everyone you can see seems fairly occupied by the arrival of the ponies.
