Savannah was still here, and he could see that she was breathing. She was safe. Copernicus had no reason to hold back against this anon any longer. They would regret harming his friends, and trying to threaten him within his own home. He would return to check Savannah’s vitals more carefully in a minute, but first he needed to use the last of his dwindling time to initiate the next phase of his plan.
Copernicus teleported back to the stairs that attached the upper dome room to the floors below, opened a control panel hidden in the wall near their base, and pressed a specific sequence of buttons.
The Observatory roared to life; steam hissed, and the sound of mechanical gears rotating reverberated throughout the metal walls. The lockdown procedure had been initiated: metal blinds rolled down over the few windows on the lower level, and an especially heavy metal door slid across the part of the Observatory floor that opened to the stairs leading below, letting out a loud metallic clang as the opening was sealed shut. As an additional precaution, the entire upper building rotated 30 degrees, causing the floor to turn and cover over the already heavy metal door, leaving no indication that there were even stairs to begin with, and effectively sealing the two sides of the building off from one another.
On the upper floor of the Observatory the skylights also became covered in heavy metal shutters, however Copernicus chose not to initiate the main door lock; He would prefer the anon leave his home than trap them inside, and had therefore left the exit open.
With multiple layers of heavy materials between them and the anon, Copernicus knew he and Savannah were well protected in the lower apartment. He had built these walls, and that locking floor, to withstand a second Thinner Disaster. It would take a lot of fire power to break through what now separated them from the villain anon.
Knowing that help was on the way and that he was currently safe, he called the local Wasteland police station and sent off a text to Gyro, before finally returning to check Savannah for any serious injuries.
