Septimontium

Septimontium (セプティモンティウム), also known as the 'seven hills' (七つの丘), is a group of seven 2nd Generation Faith Organization Objects, stationed to protect the home country capital.

Etymology
The Septimontium's name(s), both as a group and individual units, are derived from the, known in Latin as Septem colles/montes, and the proto-urban festival  celebrated by the communities that lived on those hills. The seven hills (with Latin in brackets) are (Collis Aventinus),  (Collis Caelius),  (Mons Capitolinus),  (Collis Esquilinus),  (Collis or Mons Palatinus),  (Collis Quirinalis), and  (Collis Viminalis), the latter of which unit Viminalis 02 is named after.

Design
In its attached state, the majority of a Septimontium is a 200m tall cannon, which could be mistaken for a high-rise structure in its standby state, that runs along metal rails, with the spherical reactor and cockpit connected into the base.

In its detached state, a Septimontium is mostly just a reactor and cockpit contained in a sphere less than 10m across, with ten spring legs similar to those of insects, a tail-like section at the rear and three prongs at the front for the power plug.

Technology
Operated by the Faith Organization Home Country Defense Force to protect the capital Rome, the Septimontium are effectively colossal gun emplacements mounted on metal rails through and around the city, including the outskirts and the mouth of the Tiber. To avoid the taboo surrounding specific uses of JPlevelMHD reactors and stationary cannons for defense as a result of the massacre in the Northern Restricted Zone, the Faith Organization used a loophole by insisting that they were mobile Objects rather than stationary cannons. Restricted to set paths and being only able to move along the rails at the speed of a scooter, the Septimontium cannot keep up with the high speeds of a conventional Object battle in this state, and as such have to win in a single shot.

The Septimontium's main attack, meant to eliminate enemies in one go, is a rapidly fired barrage of laser beams, fired from the cannons via the main barrel and multiple smaller openings on the sides. From seven directions, over 10,000 or nearly 10 million beams fan out at a high density, producing a wall of lasers to tear through an entire space rather than aiming at an enemy and targeting a specific point, such that enemies cannot avoid or defend. However, there are loopholes in the system, such as using an Object-sized obstacle as a shield or by using methods of bending the lasers' path in order to create gaps in the wall.

The Septimontium are capable of ejecting the sphere containing the bare minimum of the reactor and the cockpit from the base of the main cannon, turning them into what could be called the world's smallest Objects. Lacking the normal level of protection that most Objects have, with armor likely no more than 3cm thick, it prioritizes evasion over defense, with special springs installed in its six insect-like legs for rapid movements and zigzagging evasive actions. The tail section is capable of not only acting as a balancing weight, but also a hand to grab or throw things, or support the rest of the Object. Aside from the high-speed battlefields of regular Objects, the detached Septimontium is also capable of quickly navigating urban environments, as part of its other role.

The Septimontium's other role is as an internal discipline weapon, meant to deal with internal enemies and control the populace through fear. The reactor's output, normally used for the colossal main cannon, is focused on the three prongs at the front, that normally serve as the power plugs to send power from the reactor to the cannon, with pure electrical energy being used as a weapon (lightning being symbolic of divine punishment). This, coupled with the Object's design, movements and urban navigation capabilities, was meant to intimidate, scare and keep the people in line through fear.

Doomsday (Part 1)
During the 37th Mobile Maintenance Battalion's operation to thwart Bad Garage's plot to cause a disaster in Rome to prove the theory of environmental destruction by Objects, the Septimontium were deployed to destroy more than 200 cruise missiles fired at the city by the Chain Cutters. It then moved to the mouth of the Tiber, against the Baby Magnum and Gatling 033 who were approaching to support the operation from the sea and distract from the group in the city, rejecting the 37th's claims and believing they merely intended to disrupt ritual festivities, as indicated by the pilot of Viminalis 02.

After the Baby Magnum and Gatling 033 managed to exploit vulnerabilities and gaps in the Septimontium's laser wall to get close enough for direct shots, the Septimontium detached their reactors and after a period of evasion, headed into the city. They surrounded and pursued Quenser Barbotage's group, but were eventually impeded due to circumstances in the underground train tunnels.

When a tectonic disaster was triggered by the presence of many Objects in the region, with the seven Septimontium, the Baby Magnum and Gatling 033, and additional Objects arriving as reinforcements, the Septimontium were caught up in it, with Quenser observing a wrecked one as his group emerged from underground.
