You declare to the refugees that you will kill the trolls, which is received by a mixture of incredulity, shock and even a little desperate hope. Still, they are happy to give you directions to their village, which is broadly on your way to the mountains, and even follow at a safe distance.
You clamber up onto the top of the hill that overlooks the valley this village is in. The sun has just set, and starlight has begun to illuminate the town. Down below you can see that the village is largely abandoned, but of particular note is the black cloud in the centre; so it seems at first. You realise that the black is from hundreds of crows, and as one of the village doors opens with a bang the crows all take off, revealing a pile of scores of dead bodies, piled like cordwood.
A huge figure, twice the size of a mortal man, emerges from the house, seemingly carved from living rock. He looks like a statue, but a statue that has seen the wars. Where once a proud nose and strong jaw were apparently chiselled into his face, time and damage has left it so filled with scars and pockmarks that it appears to be a monstrous grotesque of human features. The troll picks up a body from the pile and bites its rotting head off with a massive mouth, filled with what appear to be shards of rock for teeth.
A - Kill kill kill kill kill the trolls, hunt them down there shall be no clemency!
B - Study this village a bit more, see if you can scout out any useful information.
C - On second thought, trolls look dangerous. Let's get out of here!
