Giratina didn't know how long it took to get to the Ultra Beast ruins, but eventually he made it.

The bodies of the Pokémon from Crystal's army were still here. His heart twisted as he remembered how desperate Xerneas was to bring them back before Necrozma sent them into the future. It hurt knowing that Xerneas couldn't bring them back at the moment, but there were more important things to worry about for now.

Giratina found the prism shards in the center of the clearing, shining in the sunlight with pale colors of the rainbow. He landed, observed them for a bit, and caught a flicker of diamond blue movement in the corner of his eye.

He turned around and saw no one there, but Giratina found himself staring at the empty space for a while.

That seemed… so… familiar… somehow…

Giratina shook it off and turned back to the prism shards.

He slowly started picking the shards and cupped them in his shadow wings. They started to glow slightly before they absorbed themselves into Giratina's chest, leaving it glowing for a bit before it disappeared.

Giratina flinched, the shards were really cold, even as they absorbed into him. He shook it off quickly and started to fly back to catch up to Xerneas and Regigigas.
