From 1KM1KT description:
We are the Sabbath Ghosts. Devout Jews preform no work from sundown Friday until Saturday night. No switches are flipped, no coin changes hands, no creature harmed. But our enemies do not rest on holy days.
Thus the Rabbis of of our colony have made dispensation. Each member of our group is officially dead and symbolically buried. Upon rising from the shallow crypts, we are spirits, exempt from the laws that bind men. Neither the grace of the sabbath bride nor the nor the commandment “Thou shall not murder” prevents us from doing whatever is necessary to safeguard the children of Israel.
Shema Yisrael! If you come to Saturn, spirits protect you.
