From Gineipaedia, the Legend of Galactic Heroes wiki
The following is a list of unnamed Terraists.
During their infiltration of Terraism Religious Headquarters on Earth in 799 UC (1 NIC / 490 IC / 3599 CE), Olivier Poplin, Julian Mintz, and Louis Machungo discovered that the poison thyoxin was being secretly administered to the cult members. Eventually, after avoiding the drugged food for some time, they were summoned to an infirmary, where a doctor attempted to forcibly inject them. However, he and his guards were over-powered by the three intruders. (LOGH: 'Holy Land')
