Glarondar was vital to Aglarond's security, especially from Thay and constant fears of invasion. The Simbul knew its importance and made sure to finance the fortress's upkeep and kept its garrisons equipped and supplied.
The town surrounding the fortress reached 1,000 citizens by 1368 DR. Most settled on the western side of the black rock structure, away from the dangers of Umber Marshes. Most civilians of Glarondar worked on supplying and entertaining the garrisoned soldiers. A large chunk of the population was half-elves who lived among humans with few to no conflicts.
Due to the high half-elf population, they often traded with less-civilized half-elves from Yuirwood.
