I'm seeing some Kingdom Hearts themes in the new Targon lore

Leona = Sora Her personality resembles perhaps a more tempered Sora and not the happy-go-lucky one we all know. Her aspect reflects a Light theme, and her shtick is protecting her friends and the weak. She's also searching for:

Diana = Riku Her personality is dark and brooding like Riku's with the same hair color even. She wants power, and while the moon gives light, the night is about darkness. Additionally, her weapon is thematically similar to his (though his could be thought of as 'corrupted.')

Pantheon = Kairi As in, 'post soul ripped' Kairi in Hollow Bastion.

Maybe I'm looking too much into this and being clouded by head fanon, but I honestly wouldn't be surprised at this point if one of the other two grey circles turned out to be based on Ansem and the other on King Mickey (or Donald and Goofy)
