Minz is an evil druid that used the tower in Femor Hills to imprison the lady Caramellia. He cast a spell so that tall grass in front of the tower would grow up fast as soon as it is cut down, to prevent people from entering.
According to Caramellia, he spied on her and her lover Winfred and suggested her imprisonment to Caramellia's father, who had forbidden Caramellia to see Winfred.
