After "In My Hands 2: For Eternity"

Xevn Kiguri Alkaid
Once the battle was over, Xevn said goodbye to everyone and left the world of In My Hands, not intending to return. He met with his younger brother, Nocte, and the two of them together when on a worldhopping spree, along the way Xevn meeting the woman he would eventually marry, Natalya Faolyn. Eventually, they decided to settle down, and moved in to live with Xevn's older brother, Unire, who had almost raised him and Nocte after he had killed their father for endangering his little brothers' lives.

Ignis Harvey
After the battle with Ashburn, Ignis left to his own world. He went back to his former love, who rejected him for leaving in the first place. Cowed, but much more serene from his journeys, Ignis took the rebuke gracefully, and left once more. He was targeted by an assassination party to kill him and his friend, Enola, however Ignis was more than enough to defeat all five of those who attacked, four of them dying in the process. The fifth lived, and grateful to Ignis for sparing her and defending her from those who wished her dead in return for what she had almost done to them, she thanked him, and defended him in turn when her superior arrived to finish the job that she and her former squad had failed in. The two of them eventually started a relationship, and wed.

Alexandra "Alex" Mayer
After Team Eternity was defeated, Alex went on to become a powerful Pokémon trainer and also began leading a fairly public life as a motivational speaker and "politician" of sorts, unlike many of the other Communicators, who preferred more private lives. Not long afterwards, Alex married the Communicator of Entei, Aidan Rhys, though they ended up having no children. The two settled down in Anura, and Alex worked hard to establish Anura's government system, which she eventually became the Champion of. Alex stayed in contact with most of the other Communicators after the fall of Team Eternity and would maintain strong relationships with most of them, especially her twin brother, Luke.

Arietta "Ari" Rei
After Team Eternity fell, Ari needed an escape. Day, her brother, the boy who had been her second family, was dead, killed in the battle. Konoe, her sister, the girl who had always made her smile, had returned to Birth Island without a word to any of the Communicators. Alita and Luke, her sister and her sister's new boyfriend, would probably forget about her soon enough. So, the girl begged her Bonded Legendary for a way to leave, for a way to start over. And Meloetta, the Pokémon who valued freedom more than anything in the world, decided to help Ari. While the walls of the universe were still crumbling, resulting from Arceus's sudden death, Meloetta sent her Communicator away into another world, bidding her good luck. And when Ari opened her eyes again in a whole new world, she was in Reliai... and her story was not nearly finished yet. Changing her name to something new, Ari would become someone new.
