Keep in mind that no map is fully developed yet. You have to imagine the cities are much bigger than what we can see in-game atm in order to consider realism, that means there should be room for rogues to hide from the guards (back alleys, dark streets, sewers, rooftops, etc.), except for the rogues that are right in front of them (which should be moved, if there are any).
After all, the Ortarchy rules with an iron fist all over Yliakum and has the manpower to enforce its laws everywhere. It would be more unrealistic not to have guards at all in Ojaveda.
