Kai Latra's Sith poison

In 1,387 BBY, the Kai Latra created an alchemical Sith poison for Darth Saleej. The toxin was intended to assassinate Phnyong; Latra designed it based on various s he found in holocron records, including  toxins. Darth Alecto spiked the wine at the graduation ball with the poison and successfully assassinated Phnyong and a number of other Republic leaders.

Kai Latra gave Alecto two syringes disguised as hair sticks, telling her that one (with a silver tip) contained a cure, while the other (with an onyx tip) contained a serum which would cure the effects of the poison but sever the recipient's connection to the Force. However, Targere prevailed on Latra to fill both syringes with the false cure. Alecto, who had been compelled to drink the wine to blend in, administered the silver stick to herself. She gave the black stick to Tirien, who gave it to Narasi for the Chancellor; seeing the Chancellor already dead, Narasi administered the serum to Tirien instead.

As Targere had intended, Alecto lost her connection to the Force, as did Tirien. Over a month later, the two teamed up to infiltrate the Palace of Happiness, confronting Kai Latra and forcing him to hand over the antidote. He had made only one dose, but Tirien allowed Alecto to use it so he could race to save Narasi and Aldayr Nikodon from an ambush by Xargo Dejuth and Sanno Casa. When Narasi saw him and made to help, Tirien believed she would die if she wasted time, and surrendered to death so that she would flee. The fact of total self-sacrifice was so rooted in the light side that it broke through the poison's effect and restored Tirien to the Force. Meanwhile, Alecto drank the cure and also had her Force powers restored.
