The Apocalypse World was the property of the Coincidental Luck System. And, since it was a high-quality Mental Energy farm with the most sought-after Host to the Luck Systems, Rhizen, all the Luck Systems gathered to gain ownership of the Apocalypse World from the Coincidental Luck System.
And, they cunningly sent in Hatchling Systems that were all useless for the Coincidental Luck System's growth. Devouring them would only end up injuring itself. And leaving them to their own devices would lead to Rhizen's death sooner or later, as it had already happened many times.
As it didn't know of his scheme, it believed that the moment Rhizen knew of its existence, his mind would be so much affected that he would lose all capability to harness the power of luck. In truth, this was Rhizen's ploy that he executed once, making it believe so from thereafter.
