So, I copied the following from a post I made on HWP.
Okay... I'm going WAY out on a limb here:
Cortana's first words were, "When the game is over, the King and the Pawn go in the same box."
Now, read this excerpt from the site.
The highlighted text translates to "When the game is over, the King and the Pawn go in the same box."
Coinkydink? Maybe, maybe not.
Could it be that Halsey has Vinnevra's geas, and it was awoken in Cortana. Who, then, is Aurora? Maybe Chakas? Maybe someone else?
