It was around sunset by the time Giratina, Xerneas and Regigigas made it to Kyurem's mountain. There were occasional faint rumbles in the ground, which Giratina soon realized that it was because of the mountain that was beginning to fall.
"You said Kyurem's mountain will fall and that's how Necrozma is able to absorb the world's light, right?" He asked Regigigas. He nodded and stepped forward. "Yes. It's only a matter of time before it happens, even though it doesn't seem like it's going to happen now."
"There's no doubt that Necrozma's hiding so he can wait for the mountain to fall." Xerneas pointed out before looking around and then pointing to an area of small mountains in the distance, almost in a complete circle. "That place seems close enough for him to hide and wait. He could easily fly to the mountain and find the source of absorbing the world's light."
"Well, then let's go before Kyurem's Mountain falls." Giratina said, before starting to head to the circle of the mountains, hoping Xerneas was right and Necrozma was hiding there.
