Erfworld "Men" resemble real-world humans, except for their smaller size and the ways in which Erfworld mechanics create difference between Erfworld situations and corresponding real-world ones.
The name "Men" is generic; they appear in both sexes, despite the fact that new units in Erfworld are created by cities and appear as newly-minted adults.
Stated in Parson Gotti's Klog, Men are the only units which have Cities, Royals, or Nobles.
