Microbe
Life below the edge of ordinary sight: bacteria, archaea, many protists, the drifting film.
description
Most living cells on Earth are not trees, whales, or humans. They are microbes. They fix nitrogen, ferment, infect, and photosynthesize. They invented the chemistry everyone else inherited.
Plankton, bacterium, Yeast as cell, and virus-adjacent worlds on the map feed Microbe. It is the broad attractor for unseen life, so the card does not need a type for each strain.
