Where do these "rumours" appear? When you arrive in a region, or do you specifically need to do the "listen for rumours" action?
So I have been tracking a wizard on dwilight for near three months now and have not yet seen a pattern develop on his movement. Just how long is that going to take? 3 months RL seems like a long time to not have discovered a route a of yet. Sages and wizards are still run that way correct, and not random like long ago?
No one ever said they have a fixed route, much less a close one. However, they do have a route, i.e. they don't just disappear here and appear there, but travel around.
