Aliens are the "silent enemy". They live among us, below us, overhead, and in space. There are multiple species, there are factions, there are alliances, there are arrangements.
"Humans are the most valuable commodity in the galaxy."
We are grown like crops, we are traded on markets, we are targets of politics and games, we are experimented on, we are possessions. Those of us who are lucky enjoy the freedoms we take for granted every day.
Somebody prove me wrong.
