In the opposite direction of Sol, is city of Cetum, a city ruled by a subrace of Nefris called Sirus.
Sirus are nefirs born from the marriage of simir and sapinsar, the originals.
As hybrids born from both ruling races, one can imagine the social standings of Sirus. In the beginning, they were considered the purest blood offspring.
Hence over time, as everyone around them respected and loved them, they started getting spoiled. So much so that an ego that others are lower beings, made just to serve them, started coming into their hearts.
Obviously the more this superiority complex grew, the more their racism and hate crimes against others started.
Thus leading them to be hated by everyone over time.
The proud Sirus couldn't accept this 'rebellion' of lower caste, so they tried their best to cull it in the curb, by causing senseless killings in the name of punishments. Making others to hate them even more.
