Daerlun is a heavily fortified city near the border between Sembia and Cormyr, once Sembian, later Cormyrean and in the end a neutral city-state.

Overview
Daerlun lies in western Sembia, close to the Cormyrean border, with the Thunder Peaks some two dozen miles to the north. It is one of the oldest cities of the realm and a natural stop for caravans travelling between Cormyr and the Sembian coast.
It is the most heavily fortified city of the region, with a towering curtain wall of magically hardened obsidian raised by the Netherese. After Netheril's fall the city was annexed by Cormyr, and later declared itself a neutral, independent city-state. Because of its closeness to Cormyr, many of its families have relatives and trading partners across the border, and the city has a more traditional feel than the ports of the coast.
In adventures
Daerlun is a good base for adventures along the Cormyr–Sembia border and in the Thunder Peaks, where bandits and monsters prey on caravans.
At the table
- Bandits in the Thunder Peaks have been striking caravans with suspiciously good information about their cargo.
