Dhalmur
From the outside, Dhalmur seems like any other dwarven town. Its hidden beneath the mountainous terrain of Gildreda, lit via bioluminescent plants and magic, and filled with hard-working and steadfast people. There's a royally appointed mayor with an elected city council.
However, about 5 years ago, a mage moved into the city and erected a magnificent tower. Hundreds of people flock to the mage daily for help with about any problem. They hold more power and influence than the official leadership of the city, and use it for their personal gain.
Ask any citizen of the city, and they'll tell you that the mage is the best thing to happen to the city....even if sometimes people go missing after visiting them.
