Hm. A terribly familiar story. Perhaps it will come back to me soon enough.

[Riley's hands stopped glowing with aura. Lucario is still sniffing at the Pokedex, but at least he seems pleased. Hilda seems nice enough so he puts his paws together and bows to her.]

You have three of Sinnoh's treasures. There are three dragons that hold the world in balance, so the myth goes. Dialga, master of time. Palkia, master of space and Giratina for the netherworld. They each have an orb which is linked to their powers. And it seems, Hilda... that you have to come into possession of all three of them at once.

[Nope, not explaining himself. He's still trying to remember why that story Hilda told him was so familiar.]

Pardon the urgency but there are forces who would want these and not for good. They need to be returned before... oh.

[Riley trails off as stops, then adjusts his hat. That's why it was so familiar. He murmurs something along the lines of "Ghetsis Harmonia. N's father..." before shaking his head and speaking at a normal volume.]

Ah, I do apologise for my scattered thoughts, this discovery has me rather shaken.
