The world of Jer and the place beyond the Spatial Gates are vast, there are too much abominations with varying levels of power. Through the intense research of Abomination Inspection and Analysis Bureu(AIAB), humans came up with a grading system to better understand these abominations. The stages of abomination evolution is as follows:
-Rank 1
-Rank 2
-Rank 3
-Rank 4
-Rank 5
-Rank 6
-Rank 7
Feeling that the ranks assigned was too broad, they then added an indicator of threat level/potential. In order from lowest to highest they are; Red, Orange, Yellow, Green, Cyan, Blue and Violet.
Every Rank consists of corresponing tiers of threat levels and also those that are either a tier higher or lower tiers. The seldom abominations that do not follow this trend are called Aberrations.
