Well, Ojaveda itself is infested with rogues, something that is by far not realistic either. It has the distinct feel of a doomed city, with most shops deserted, rogues wandering freely and not a single guard in sight. Does this mean that Brintec is a fierce fighter, so that he not only survives without bodyguard, but even is able to keep his shop open without any defense at all?
Also, the distance between Hydlaa and Ojaveda is short (though longer than it is ATM). Also, the first and second levels are more or less farmland according to the settings. This means that most places are
not infested with wild beasts.
All in all it seems like the MOBs got put there because there isn't much space.
So what can one expect to come accross? IMO, at night, a clacker or a rat. Anything else would be a rare thing on the major roads. In daylight, probably a lot less even. Both Ojaveda and Hydlaa have a garrison, so they'll make sure the vincinity of their cities and the important roads are free from marauding bands, too.
@ Garon: Agreed. And yes, the loot distribution indeed makes one wonder at times. Especially if the rogue has a silverweave sword, then how come he didn't do the appropriate damage? Was he not using it because he feared to degrade it?

That, and that you can loot money from a Trepor (swallowed it alongside the original owner?)...
