There is a multiverse in my mind, where characters and plot lines cross paths and realities to merge by way of tropes.

Sentinel Stories–The trope of a mystical warrior with super-strong senses and the yen to protect the tribe, and the empathic supporter who stands by him (or her).

The Carrier ‘Verse–Due to natural evolution, there is a small percentage of human men who can carry and deliver live births.  In this universe, Carriers, or “Thirds”, are revered by many cultures because without them humanity would have died out.  There is also in place a special think-tank dedicated to protecting and nurturing child-geniuses so they can thrive in academia without burning out or isolating themselves.  These two worlds often cross.
