Hideout of the Silent Blades, home of the Cloak & Dagger
" 'Tis just a cave, yeah, but a cave with a lotta history innit..."
Famous home to the Cloak & Dagger tavern, and also secretly home to the Silent Blades, Devin's Retreat is a small artificial cave system under Blackbourne, following the Black River. The mouth of the cave is praised by the exotic vista it creates in union with the tavern.
The river was already fully recovered a couple centuries later, when between Krenjor's attacks at Blackbourne and the Artalgnian Empire's rule over the land, a man known as Devin lead some civilians into the underground where they would be safe. Through decades they dug tunnels to accommodate more refugees, expanding the place.
With this, the small cave system was formed, covering the surroundings of the main cave where the Black River goes through.
