A war waged many years ago, humans gone and pokémon left to pick up the pieces. Though like so often in these stories, when is humanity ever truly gone? One person wakes up generations after those old events and finds himself in an unknown old/new world. Together with a new found friend he sets out on a journey in search of the life, he thinks is still out there... or at the least attempts to.
@MercenaryX: Well thing is I planned a little bit too much for this one chapter all under the hood that they would be stories told at the fire, but put too many events in one basket so no actually no new chapter for a bit still and a few more guiding flashbacks yes.
And I have not seen Detective Pikachu yet, don't know when I will, so any to be inspiration from it will be seen in the future :)
And mewto hmmm.... a few other legendaries are planned for sure, but no mewto up to this point yet
