After they completed their Advancement Quests and Samiel managed to germinate the Ability Seed in record time due to the outside help from the Outer Gods, they observed how the Void was enveloping the Divine Altar dedicated to the Outer Court.
It looked like some sort of crystallization took place around the entire structure, looking like some protective shield enveloping all nooks and crannies of the Divine Altars of the Outer Court.
Probably some sort of mechanism so nobody under Legendary Level would not even dream of damaging this splendid piece of architectonic wonder that he scrapped up together, but that was not his matter at all.
When they were done here, Samiel contacted Juulius and they started coordinating their effort to clean out the remaining factions of the Bone Mountains so the Holy Sunz Klan could take root in this place entirely.
