Chairman Gregoroth (グレゴロス議長, Guregorosu gichou^?) is the head of the Imperial Senate in Final Fantasy XII. After the Senate corners Vayne Solidor, the heir to House Solidor, he poisons his father, Emperor Gramis, and then blames it on the Senate. Gregoroth is supposedly the head of this plot, and is said to have confessed, then committed suicide.
