It seemed much of the knowledge that humans had of the floating land masses they called Nests were in the wrong. The landmasses were called Spiritual Lands by the knowledgeable ranks of beasts, with the dense essence that continued to birth monsters being a constant trial of power.
It was a brutal trial where those that were defeated were used as the fuel for the victors to continue rising. After a significant time period has passed where higher ranking beasts appear, the Trial of Supremacy will take place.
This trial differed depending on what tier the Spiritual Land was, with Tier 1 blessed lands having trials most fit for those just entering the EPIC level. Only those at that level or lower could possibly participate in the trial, with anybody above it being qualified.
