So I found a random traveller, a simple farmer with a cow painted in woade saying he was delivering the cow to the Giants so that they will stop preying on his cattle. Naturally I asked if I could help and he said no, that I'd only get in the way and he knew what he was doing. Anyway, I followed him all the way to the Giant camp south of Windhelm... he walked over to the Giant who then sent him into orbit, killing him instantly leaving the cow alive while a similarly painted cow roasted over a fire. I killed the giant, as a simple matter of habit but had little sympathy for that farmer who so eagerly walked into his own end.

It was pretty funny though, anyone else find this guy? Its totally worth following him.

It's a normal random event.

Safety tip:

Don't paint your cow with the wrong symbols!
