The Church of the Lightning Stone was a Christian church on Terra during the Unification Wars. It contained the Lightning Stone, a relic reputed to have healing powers. Its last caretaker was by the priest Uriah Olathaire. The Church had the dubious distinction of being the last place of public worship to be destroyed by the Emperor's warriors. Its destruction was overseen by the Emperor personally, who, in the guise of a simple warrior named Revelation, engaged Olathaire in a debate about the relative merits of religion and the Imperial Truth. At the conclusion of the debate the church was burned to the ground and Olathaire, despite being offered a place at the Emperor's side, chose martyrdom in the flames.

雷石教堂是统一战争期间泰拉上的一座基督教教堂。里面有雷石，一种被认为具有治疗能力的圣物。它的最后一位看护者是牧师乌利亚·奥拉泰尔。教堂有一个可疑的特点，那就是它是最后一个被帝皇的战士摧毁的公共礼拜场所。它的毁灭是由帝皇亲自监督的，他伪装成一个名叫启示的普通战士，与奥拉泰尔就宗教和帝国真理的相对优点进行了辩论。辩论结束时，教堂被烧为平地，奥拉泰尔尽管被安排在帝皇身边，但还是选择了在火焰中殉道。
