Reward: 500 Renown, 2000 Gold.
It's time to head a little bit further to the south. Your goal is to escort two traders to Barrow Fields through Darkwood.
Very soon after talking to the traders, you will meet a wounded man that asks you to let him join your party and venture together. Rejecting him will give you some negative alignment points, and if you decide to take him you'll have to fight him at the end of the mission. He's infected with the Balverine disease and will morph into one of them.
Darkwood, Darkwood Marshes, Darkwood Lake, Darkwood Camp (you can get some supplies in here), Ancient Cullis Gate, Darkwood Weir - these are the regions you'll have to cross in order to get the traders safely to Barrow Fields. When you see white mushrooms in your way (shown at the screenshot below), shoot them with an arrow. Balverines are much tougher than Hobbes, but aren't a real threat for you as long as you have some potions ready.
By the end of your journey, you will encounter a mini-boss, an Earth Troll. Dodging is very useful against this guy, as you might get hit by his rock attacks if you don't move fast enough.
When the Troll falls, go to Barrow Fields at last and finish the mission.
HINT: It's good to return to the North crossing the Darkwood regions again, as there are some interesting things hidden in there (silver keys, chests, demon doors), which you supposedly missed due to the traders' company.
