The Chosen Children in my world are much like the tamers in this world: they were chosen to fight a war in another world they were poorly-equipped to fight. These Chosen Children aligned to specific crests which represented their strongest attribute. Courage, Friendship, Kindness, etc. I was Darkness, and because of this, I was barred from ever entering the Digital World because the Powers That Be were afraid of me siding with the badguys and/or Millenniumon. Then I started dating Millenniumon's partner, which made me more of a pariah, then we sort of became the dirty little secret of the Digital World: spoken of in secret but never officially acknowledged, often regarded in fear.

Fortunately, I've apparently been dead in all but one of the other realities, so the Chosen Children in those universes didn't have to worry so much.
