The Guard Palace nobles would not fear a "demotion," but the situation was different for the inner palace nobles. The Noble House had a stringent criterion for them: the situation of Mage training. For every Mage trained, a certain number of points was obtained; the points for silver, gold, Holy Domain, and Legendary all varied. Simply put, Dukes had to train a Holy Sanctuary Mage every thirty years to extend their noble status (Holy Domain from generation to generation), while Viscounts could relax this to every one hundred and twenty years (Holy Domain every four generations).
