Blüdhaven

Blüdhaven is the city that Nightwing protects as well as Gotham City. Located not far from Gotham, Blüdhaven's crime rate is almost at Gotham's level. Nightwing has encountered many criminals there including some of Batman's enemies.

Blüdhaven is never fully seen in the series but has been mentioned numerous times by thugs until the last game. Nightwing talks about it in Batman: Arkham Knight. In Batman: Arkham Knight, the Harley Quinn DLC is set in the Blüdhaven Police Department, and the GCPD Lockdown DLC has a part set at a warehouse near the Blüdhaven docks. It was also given a mention in A Flip of a Coin DLC, revealing that Two-Face's Gang was robbing various banks there as a fall-back plan in case their attempt at robbing banks at Gotham failed. Nightwing was out of town because he was attempting to stop Penguin's weapons laundering business through North Refrigeration.

Blüdhaven was a former whaling town, which was officially incorporated as a "Commonwealth" in 1912. The town had a generally poor socio-economic populace, owing in part to failed efforts to transform itself into a manufacturing and shipping center.
