Gaia Volume IV
The Wyred are those Silothreni who possess the Talent (for magic). They compose about 5% of most houses. They can be born noble or servant, but when their magic potential is detected they become Wyred. The status of Wyred in relation to Nobles and Servants is ambiguous. Although technically they exist outside the caste system, they benefit from the labor of the Servant caste, and are subject to the commands of their house Patriarch. Wyred may come and go as they please, but they typically reside on the property of their house or in the Labyrinth, the Wyred stronghold. They have their own governing bodies and most houses treat them as outsiders unless they are needed.
