Venedikt knew that after their performance in the yearly competition, his sect had become popular overnight. And popularity, whether wanted or not, always drew attention both from new rivals and from old enemies.
His disciples only wielded incomplete aspects of the Void, fragments he had given them after going through a great deal of trouble.
He did so because, though it risked exposing the presence of the Amorphous Void codex, he had no other choice but to do it if he wished to complete his epochal trial.
Venedikt took such a risk not because he feared the minor penalty of losing his law tokens, but because the trial offered an invaluable reward.
The second epochal trial offered many things: a high-grade Ruler's Wish, Law Tokens, but more importantly, the location of the Amorphous Sect's monastery.
It was Xnoura who told him that, while she did not know all the details, the monastery was the second most valuable thing their sect had possessed, second only to the Codex itself.
