The Northern Government

The Northern Government is one of the main forces in the current war. Known for creating Humanforms, their main religion is Ruikonism guides most of their actions.

Political Structure
The Northern Government is a theocratic monarchy lead by an emperor in theory. However, the monks that live in the diamond tower are the ones who has actual political power. They rule from the Diamond Tower. It is the Sannova family that is tasked with birthing each new emperor.

The task of each new emperor is to fulfill the prophecy that was foretold in Ruikonism, that being to kill all of the devout believers in the Quickening Chamber and to avenge the good believers who were oppressed by heathens. It's like Karma, but the believers need to sacrifice themselves to punish the wrongdoers.

Due to the fact that Lady Sannova, the woman who was burdened with birthing the new emperor, only birthed a stillborn, the stillborn was fused with an artificial Hiruko to keep it alive. Because of this event, Lady Sannova was exiled from the court and had the Sannova bloodline declared as impure. This were the circumstances that the Hiruken Emperor was created in.

Religion
They practice Ruikonism, one of the biggest religion in this world. There is one notable holy site in the empire called the Quickening Chamber. Every year, new pilgrims arrive to the Quickening Chamber to wait to be sacrificed. The Quickening Camber has a very long, huge staircase that takes two days to go down to prevent people who aren't devoted to the belief from reaching the core.

Military
Most of the Northern Government's strength comes from their use of Humanform Weapons. These Humanforms are usually commanded by a Humanform pilot via the control ring on their necks. In addition, the Northern Government also possess normal human infantry. They don't wear helmets, but instead only wear a face-covering to cover their face. They have religious symbols painted on their forehead. They also wear short, red robes, white, lain pants, and black boots. Their main weapon seems to be a fully-automatic rifle that looks like an AK-47, but with a non-curved magazine.
