[@Ruby] In this timeline, did Wolverine died in 2018 instead of 2014? Like what Earth universe should we read to gain some insight about the background? That is what I am asking if the question confused you. Sorry for my wording.

Logan died in 2029, we're picking up around 2040.

All you really need is a basic understanding of mutants, the X-Men, and it would help to have seen the movie Logan.
