At some point, Wolverine, headmaster of the Jean Grey School for Higher Learning buried a time capsule along with the students and the other teachers. Twenty-five years later, he found this capsule, having forgotten about it, and decided to warn his past-self of what was coming for him.
He teleported to the Space Station X to use the time travel technology stocked there to send a message to his past-self in order to prevent some events from happening they did. Eye-Man, warden of the station, first tried to prevent him from doing so, but ended up helping him defeat the Archangel Bots guarding the vault containing the time travel tech. Eye-Man convinced Logan that his past-self didn't need help, asking for Logan to thank his counterpart. Logan sent a message only composed of thanks, a good luck message, and the key to a safe he found years ago in Dog Logan's cabin.
The message arrived right the moment Logan was digging for bury the time-capsule, and past-Logan used it on the safe, finding old toys he and Dog used to play with.
Seemingly those of the James Howlett of Earth-616.
It had been speculated that Rose Logan may be his daughter or his niece (daughter to Dog Logan).
