PURE Vessel

Creation: The Pure Vessel was raised by the Pale King to serve as the perfect, emotionless vessel to contain The Radiance (the source of the Infection).The Flaw: Despite being designed to have "no mind to think, no will to break, no voice to cry suffering," the Pure Vessel developed a deep, genuine affection for the Pale King. This internal conflict gave the Infection a way to leak out, which doomed the kingdom.
