There's always a need of justice - even during times of peace.
In many areas life outside of cities is tough and filled with harsh manual labor. People are fighting the nature's elements alongside wild beasts to protect their only income - lifestock, grain and vegetables. Most governing bodies in Ansium only rarely bother to send properly equipped and trained soldiers to assist people in scarcely populated remote areas. Soldiers are mostly only around to collect taxes. Still ... justice is served in many regions. In several areas of the world, liege lords hire the servants of Aldamar to act as a sort of travelling one-man law enforcement units. These adventurous individuals then travel the villages and smaller towns looking for disputes to settle. Travelling judges they are not - more of civil arbitrators whose opinions and wise tales teach common law and common sense when people run into disagreement.
Aldamar's arbitrators have no official organisation. There is no initiation, training or fee to pay to become one and no one keeps track of them. It's very common that they are local people who have gained the respect of village elders and their task is more of a calling than a job. Of course they have no official business in doing what they do if the lords of the land don't want them around. Still even in areas where their business is outright outlawed, the toughest and most stubborn stay and continue preaching about justice and sensible laws. On the other hand, there are many areas where liege lords support them and see their work crucial in keeping the rural populace content and law-abiding. Some liege lords try to suppress their arbitrators when their opinions differ from theirs, but mostly the efforts to control the arbitrators have been futile - the arbitrators only listen to what Aldamar has to say about how to deal justice.
Aldamar's arbitrators are usually well versed in both diplomacy and communal laws. They need to be verbally talented and possess enough charisma to convince people behind their opinion. They are mostly sensible in their actions and most of them possess good skills in oratory and story-telling. They often travel a lot and thus they crucially need skills to survive in hostile environs. Some of them are very adept at combat especially if they operate in areas where their presence is not tolerated by the lords of the land.
