Following the beginning of negotiations at the Pretoria Peace Summit, the militant communist revolutionary group the Peoples' Global Communist Unification Coalition (PGCUC), lead by Adrianus Blacabus, organized a protest bombing of St. Gregorius' Cathedral in downtown Trurnia. The Cathedral was likely selected as the target for its Catholic usage and for the fact that it had long served as a symbol of Trurnian cultural unity since the Ferunian Separatist War which had racked the region. The bomb was placed by a PGCUC operative taped under the center altar and was set off during the 8:00 PM Romano Standard Time evening mass on October 12th. The explosion went off at exactly 8:34, immediately killing over 100 seated near the altar, including Archbishop of FerunicumRaurus Tullius, before setting fire to two adjoining chapels, each primarily made out of wood. The fire killed over 100 more attempting to flee the burning cathedral, several sections of which collapsed due to age of the structure. Marshall of TrurniaLuçeo Mareo immediately ordered the deployment of police and firefighters along with ambulances to counter the destruction.
