Regis is most notably featured in The Icewind Dale Trilogy, which was written by the American author R. A. Salvatore, where he is introduced as a member of the adventuring group known as the Companions of the Hall alongside Drizzt Do’Urden, Bruenor Battlehammer, Wulfgar, and Catti-brie.
Regis is a halfling who is known for his small stature, quick wit, and exceptional skills.
Although he originally hails from the city of Calimport, he fled to Icewind Dale to escape his past.
In Icewind Dale, he becomes the unofficial mayor of Lonelywood and later joins his fellow companions on their various adventures across the realms.
