A shaman like man appears out of nowhere and asks if any of the PCs have ever heard of him. They will of course say no.
He says, “Oh well, most people call me Jasper anyway.”
He then goes on to ask the PCs to save him some of those red arrows. Nobody knows what he is talking about. Jasper will go with them for awhile telling stories that don’t really make sense. In the middle of one of his stories he suddenly bends over, picks up a rock, and throws it hitting and killing a rabbit. Everybody, by rules of human nature, would look where he threw and when they look back he is gone.
Later on they are attacked by a band of brigands with red arrows. He may appear again or he may not. Just a little shake up to the norm.
