Dainty Biberveldt is a halfling, businessman and horse breeder from Knotgrass Meadow. He is Gardenia Biberveldt's husband, Arno Hardbottom's son-in-law. For a brief period of time, a doppler named Dudu impersonates Dainty in Novigrad, but despite the less than conventional way they meet, the adventure ends extraordinarily successfully for Dainty. It seems that dopplers, or at least one doppler in particular are pretty shrewd investors.
Dainty appears in the short story "Eternal Flame" in Sword of Destiny.
