The airships of the Department of Inquisition that are patrolling the skies suddenly begin to attack the city. Ion Fortuna decides that the time is right for him to make an attempt to meet with Cardinal Caterina Sforza again, calling for a temporary truce between Brother Petro and him. Meanwhile, Dietrich von Lohengrin, who is revealed to be controlling the airships, rebukes Radu Barvon for his failure to kill Ion and move forward the Rosenkreuz Orden's plan to sever relations between The Vatican and the Empire. As Father Abel Nightroad, Sister Esther Blanchett, Brother Petros Orsini, and Ion make way for the embassy where Cardinal Sforza is, they are stopped by Radu, who has hijacked a Goliath tank and intends to kill Ion with it and make his death seem like the result of Terran actions. He fires on the group and severely injures Brother Petro and Ion. Moving to protect his companions, Abel flies into a fit of rage, activating his 80% Crusnik mode and feeding on Ion's spilled blood. Abel destroys the Goliath, killing Radu in the process and appears to be heading for Ion to feed on the rest of his blood when Esther pleas for him to stay away, helping him to come back to his senses.
