Gerald of Riveyra

Gerald of Riveyra was a Torilian sage and scholar who specialized in the criminal organizations of the Underdark in the 14 century DR.

Activities
Gerald studied Underdark gangsters such as Gnormahlenvaey Catoneriehn, Vikhrumn Coll, Brikhalna Ipprszhen, Felyndiira Shi'narrvha, and Gray'shivnarien Taliain. His information found use by Sir Elliot of Kness and the Forthright Band of Investigators in Waterdeep.

Background
Gerald of Riveyra is unlikely to be a reference to character Geralt of Rivia of The Witcher series, given the date of publication. Rather, he's more likely to be named for journalist and talk show host Geraldo Rivera.
