Domain Phaath was a Domain among the Shaper caste of the Yuuzhan Vong. They were an ultra-orthodox Domain, never deviating from the Shaping protocols. However, they were responsible for the creation of the Voxyn, a hybrid of the Vornskr and a Yuuzhan Vong creature, the Fero Xyn. Hybrids of creatures from the two separate galaxies were originally conceived by Mezhan Kwaad, who was sentenced to death for heresy for this precise work. A notable member of Domain Phaath was Yal Phaath.
