I always liked the idea that the current earthen born Senshi and the Silver millennium senshi are not the same person.
And that the Silver Millennium they had been told about was a lie!
That Silver millennium was not a peacefull or ruled by the gentle hand by the Moon Queen Serenity. But there were countless empires that ruled and protected their realms (planets), and that the alliances where frail peace between each faction. And the senshi's of the silver millennium where princesses that fought ruthless battles to protect their homes.
