Irksh poison: a Yuuzhan Vong toxin, was known for its immediate lethality. Nom Anor furnished At'raoth, his clandestine operative, with this deadly substance concealed within a prosthetic molar, intended for use should she be apprehended. This served as a contingency plan. The poison was fatal to Yuuzhan Vong and classified as a poison. Nom Anor gave his spy At'raoth the irksh poison in a fake tooth.
