The Kranach quest kind of sucks, but I like to do it for that extra bit of money it gives a low level PC, which is especially important to get the Detect Traps skill once you've completed Yergius' quest; I think most of you will agree that trap detection is important for all but the beefiest of beefcakes, and even then is still a convenience to avoid item destruction and such. The problem is, I've had times where I got the Kranach quest right away and then encountered the Roving Raiders before even getting to a dungeon. Then again, there are other times where I've spent days scouring the plains near Terinyo to find Kranach; once, I spent 60 days just to find him. Admittedly, probably not the best use of my PC's time, but that's not the point. For such a sensitive quest where you can't level up beyond a certain point, it can be frustrating sometimes relying on RNG to find the dumb guy. So what I would propose is adding an abandoned campsite in the plains or forest between Terinyo and the Wilderness river. Normally when the PC goes there, it's just a burnt-out fire and a couple of simple structures, but if the PC comes at a certain time, say at noon, or some time during the morning, they can find Kranach and his band of raiders there. Perhaps Tywat could say something like "I found his campsite, but he's never there when I've looked," except more fantasy-y of course. Maybe there's a sign with a picture of the full moon on it to let his bands of raiders know when to meet up. Ultimately the exact implementation would be your choice, these are just examples.
