- "The House of Trevelyan prides piety above all other things. Second-born children and lower are expected to serve the Andrastian Chantry or the Templar Order whilst the rare magical members of the family are shunned and never spoken of again." ―Excerpt from A Brief History of Free Marcher Nobility
Originally from Qarinus in the Tevinter Imperium, the Trevelyans were members of the Soporati social class and held a somewhat prestigious line of horse-breeders. This was until an unnamed Trevelyan showed signs of magical abilities, earning him the status of Laetan and elevating the Trevelyans as a minor nobility.
This did not last long, as all of the Laetan's descendants lacked magical powers. Fearing a decrease in power, the Trevelyans fled to Ostwick and settled there.
Other than their piety, the Trevelyans are famous for their physical features. All known members of the Trevelyan bloodline carry a prominent trait which gives each member pale-blonde or platinum-white hair and purple or bright blue eyes.
