Fidus is an eighth generation Tremere and the childe of Jervais. During the Medieval era, as a mortal, he became a servant and apprentice to Master Jervais, until he got his own embrace. He was part of the Tremere coterie led by Jervais and sent against the Telyavelic Tremere. Later, he oversaw matters in the local chantry when Jervais was occupied or away on business.
