Maferath

Maferath was the husband of Andraste. Though he was her husband, it was he who in the end betrayed Andraste and sold her to the Magisters in exchange for keeping the lands that Andraste had conquered from the weakened Tevinter Imperium. According to the Chantry, Maferath did this beacuse he got tried of being second to the Maker to Andraste while the historians version is that he betrayed Andraste to rule the lands she had conquered himself. And after betraying Andraste, Maferath attempted to do this but when word got out that Maferath had betrayed Andraste, the barbarians that hads followed Andraste quickly abandoned him and his kingdom eventually crumbled. In the end, Maferath was killed by his own sons. Because of the betrayal of Andraste - the Second Sin - Maferath's name has become synonymous with treachery.
