Pevensies
I don't know of anything myself, but I don't always keep up those things, and Atlantis can surprise.
Of those involved in the mission, I believe Alicia Spinnet, Mara Jade, Lissa Dragomir, Wanda Maximoff, Hilary Becker, Sara Lance, Sharon Carter, Oliver Queen, Bucky Barnes, Clarke Griffin, Octavia Blake, Rey, Mordecai Roberts, Davina Claire, Dimitri Belikov, Daisy Johnson, Steve Rogers, Natasha Romanoff, Tony Stark, Jack Harkness, James Kirk, and The Doctor are currently here. Some have gone and come back, like us, and I don't know how many remember, but I don't know that we should exclude them based on that.
