You get off your fairly noisy boar, he is a pig after all, and slowly creep forward. You make your way through some undergrowth and among the pine trees, you get closer to whatever it was Throlu was pointing at. Going from tree to tree and undergrowth to undergrowth, you come forward about 100 ft or so. It appears Throlu has excellent perception, he stays to guard your boar.
You hear them first, clumsy footsteps of some kind of beast of burden crunching branches. It seems there is no road, and the orcs leading the thing are making their own path through the woodlands. You then see those orcs, through the trees and undergrowth, and the oxen, laden with supplies. This may well be one of those supply caravans you were told of.....
It appears to be moving south and west, generally, though you're unsure of its final location as of right now.
Most of the orcs do not seem to be heavily armored, though do sport leather armor and perhaps some metal with helmets. It seems the majority of the orcs are not warriors, but laborers. You notice that there are 8 heavily loaded oxen, trudging about their way.
You are unsure as to the exact number of orcs, but you guess it may be around a dozen or so, that you can spot.
As of right now, it seems to they don't notice you among the trees and undergrowth. Their caravan seems to be making its way south and west at a slow pace, unhurried and unworried.
There is, however, one human among them and that one seems worrying if it came to blows. He is armored in metal, far heavier than you are and he is big. He has a spear with a wicked looking blade. He walks beside the caravan and doesn't seem to let the orcs bother him one bit. It should appear he is in charge and doesn't have to give orders, or has already given them, if you had to guess.
Throlu and your boar are about 100 ft back, hidden. You are about 15 ft from the caravan, hidden. The caravan is 8 heavily laden oxen, about 12 orcs, and one scary looking huamn heading south and west.
What do you do?
