The Neo-Demon Realm granted access to Omega Laws to the race in two ways. One method is by studying the statues' runes in the Final Purgatory. Those at Rank 8 and above have all the information of these beings' existence, including their cosmic forces.
Unfortunately, to resist the spiritual pressure those statues generated, a True Will must be at least at the Sun Collapser Rank.
The other way is to use the End Legacy Hall. Every Neo-Demon got access to the hall the moment they created their Inner Law Dimension.
After the NRAI teleported him, Zatiel found himself in a massive white hall. Inside there were eighteen gargantuan sculptures with unique and powerful auras.
One had the form of an eye with a red pentagram in it, another resembled an ocean of black flames, and there was even one that appeared to be a blood moon.
