Snakevein

Up in the northeast of Faerun, situated in a mountain valley of the Galena Mountains, lies the City of Snakevein. The city was founded originally as a mining settlement as they began excavating into a large hill that resembled the head of a serpent, believing it to be a divine omen. The discovery of rich veins, both magical and mundane, brought a large influx of settlers who invested in building it up into the flourishing cosmopolitan city that exists today. (For reference I am making this take place in the location of Bloodstone Valley in the standard Faerun lore, and have reworked it to fit my setting)
