Gadderanks is a character involved in the In Aid of the Myreque quest. To protect his family from the vampyres Gadderanks works for the vampyres, collecting blood tithes from the inhabitants of Morytania to sustain their vampyric overlords. In this capacity he is accompanied by two Vampyre Juvinates.
Gadderanks is, due to his occupation, one of the most despised humans in Morytania. When the player kills him, Gadderanks drops the Gadderhammer, particularly powerful against shades (which he feared).
During the course of this quest Vanstrom Klause, a Vampyre, discovers the location of the revived Burgh de Rott and orders Gadderanks, with the Juvinates, to collect tithes from the village. The player, to save the townsfolk from vampyric tyranny and increase their prestige among the villagers, must kill Gadderanks and his bodyguards. As he dies Gadderanks reveals why he undertook the task, is chastised by the player and reveals what vampyres are weak to and afraid of. He also implores the player to protect his family from the vampyres.
