Merchants Trade Association
Merchants know no borders and travel to all the kingdoms in Mekkan. You can find a merchant trade house in every major city in the Human, Keidran, and Basitin kingdoms.
The Royal Rangers are part of the king's guard. They patrol the kingdom and usually keep the peace.
The Mage's Guild is a magical organization found in Keidran lands.
Bandits are no longer part of normal society and instead live out in the wildness. They usually attack other travelers and rarely go to the cities.
Each kingdom has it's own shadow organization. They are usually hard to find unless you know where to look.
