Somewhere...across the multiverse...
Every version of reality is different. In this one, humanity eventually evolved to have no men at all, instead reproducing with a subset of women, about 10%, having penises - once upon a time called "trans" but now just a mundane element of society.
This all-female society has spread across the stars, building an interstellar empire with incredible technology, providing its citizens with adventure and pleasure of all kinds.
The empire was incredibly advanced, with sleek FTL ships, massive space stations, and terraformed worlds. Exploration vessels discovered and mapped new worlds. Subcultures rose and fell. Splinter groups branches out, some only briefly, some forming alternatives to the empire that lasted generations.
