Hey guys, glad you enjoyed all of this, and I hope you enjoyed it as much as I did planning it. xD
First of all, to answer Garet's question. Ever since Kivir left, I decided to remove him from this part and instead say that his character decided to go with the Alpha Alliance armies. So he is not around.
As for your second question, let me lay out a small timeline, as of this moment:
1 1/2 years ago: The Silver Tribe first attacks.
6 months ago: The final defense of Gold City occurs, where the city is taken, and most of the Gold Tribe is killed, including 'Rey'.
1 1/2 months ago: The events of Pokemon Odyssey: A New Beginning began.
