That's really interesting. The power of the lore. the mind shattered part. If the whole section is tied to savathun's arrival. The mind shattered could be Zavala. I am convinced Savathun has power over him, he has been acting weird since Titan, more so than just shock or even fear. He seems to be actually acting against the guardians more than helping. Breaking Zavala would shattered his mind and the vanguard completely as well as all understood means of the hive power can effect guardians.
