Trevim Dadeferron was the first-born son of Dixon Dadeferron, a wealthy landowner from Kail. Like his father, Trevim was a critic of the Corporate Sector Authority, which was engaged in a dispute with their family over the issue of land-use rights. Unlike his younger brother, Torm, Trevim stood to inherit the Kail Ranges in the event of their father's death. However, Torm decided to change this state of affairs.
