The second thing he saw and would have noticed even if he wasn't connected to Legion-2's mind is the frequent resurrection of god seeds in front of the temple. The sight was enough to clue him in to the devastating effect that Legion-2's actions were having on the divine populace of Gemmis.
Most of these god seeds that resurrected didn't leave Gemmis. They went up to the various boots in the temple to sit. Their numbers were endless, but the temple accommodated them. It continued to grow taller to create more rooms for the god seeds.
Legion-3 was at the base of the temple, so he saw a lot of things. One particular god seed was reformed in front of the temple in a flash of light. It was a glorious scene displaying the defiance of death by gods, but the sacredness was destroyed as the god seed yelled into the sky.
"Noooooooooooooo!"
"Noooooooo."
"I worked so hard, and you ruined it."
