TP has no reason to even be making the Frigate in the anime for starters. It was created to harness Kyurem's powers. Guess which Pokemon is absent from episode N completely.
And my point still stands. Why would they make references that have nothing to do with the games they are referencing. Project F and the ice ruins are not in the games. What was stopping them from mentioning the frigate and the giant chasm directly? The anime does not make the smart references, it's a small kids show after all.
And the white ruins were made to mirror the black ruins we saw in early BW.
To right the countless wrongs of our day, we shine this light of true redemption, that this place may become as paradise. What a wonderful world such would be...
