Sidhe's Curse
Kiasyd with this flaw are closer to their fae natures than their fellows, but instead of gaining power, they gain a susceptibility to Banality (see Changeling: the Dreaming). You have a Banality rating like any other changeling and can gain Banality in just the same way (killing fae, destroying chimera of faerie treasures, spending too much time with other old vampires) and if you ever reach 10 permanent Banality, your faeries soul dies and you lose all ability are Mytherceria. Then things really get bad when all your pent-up "karmic balance" from ages of fate manipulation comes back to haunt you, with a vengeance.
