Stygian Crypts and Shining Heroes
Phaervorul, a small drow settlement deep in the Underdark, has long served the drow as a religious center and trading outpost. The drow tolerated other peoples within the enclave, provided such visitors didn’t interfere with drow customs.
Currently, Phaervorul is under attack from an army of undead, supposedly led by a new Exarch of Orcus.
Vier’gara is originally from here.
