Gaius Sextus is the First Lord of Alera for most of the duration of the Codex. The father of Gaius Septimus and grandfather of Gaius Octavian, he married Gaius Caria after Septimus' mother died. Sextus is in his eighties at the outset of Furies of Calderon, and is dark of hair and green of eye.
Furies of Calderon
Sextus is informed by Amara of Fidelias' betrayal during the opening events of Furies of Calderon. In response, he orders her to the Calderon Valley to continue in her investigation. After the Battle of Second Calderon, Sextus arrives in the valley, where he appoints Bernard to the position of Count Calderon and makes Isana a steadholder. He also gives Tavi the reward of patronage to the Academy in Alera Imperia.
