The city was named for a local human warrior, Berdusk Orcslayer, whose driving out of orcs from the Sunset Vale made it safe to establish settlements in the area. Long before Berdusk was founded two other settlements stood in its placement. The first was an elven moot hall, the second a human fishing village. Berdusk was known as the Jewel of the Vale as it sat on both the Uldoon Trail and the River Chionthar in Sunset Vale. Twilight Hall was located here, making the city the base of many operations for Harpers in the west and the north. A person from Berdusk was known as a Berduskan.
