Sistros was one of the Four Sages of Dwartii, ancient lawgivers from the dawn of the Galactic Republic. Sistros was involved in the formation of the Republic's original constitution. Sheev Palpatine admired this historical philosopher throughout his political career. As the Senator of Naboo, he recommended to Supreme Chancellor Finis Valorum to use the image of Sistros as the centerpiece of the invitations for the celebration marking the Galactic Republic's millennial anniversary. During his own tenure as Supreme Chancellor, Palpatine kept a bronzium statue depicting Sistros as a cloaked figure in his office. After he became Galactic Emperor at the end of the Clone Wars, Palpatine moved to new quarters, taking the Sistros statue with him.
