Every author tries to create their own version of the universe. It could be this universe we live in as seen through the eyes of a character, or an imagined universe, like the one I will be using in Assassin of Earth.
My Universe is this Universe, but on different planets. Earth is here but is only a minor part of the story; minor but deadly. You see in MY universe, humans are the deadliest lifeform.
We sterilize worlds, we kill life we are the ultimate antibody in this universe. So when a “disease” breaks out we go take care of it. Sometimes there are many of us, sometimes it is only one human. Lately it is only one; it turns out that we don’t travel so well. Humans don’t like the way the other races of the universe get around the limit of the speed of light. Most, in fact almost all humans, die during their first interstellar journey, no one knows why. The ones that survive have become deadly, very deadly. It is as if the journey triggers an immune response against the rest of the universe.
What does the rest of the universe look like?
It looks astonishingly like us. The universe is populated by other bi-pedal “human looking” beings. No exotic species, no other life forms, no ice creatures. Hands, arms, legs regular looking. Oh there are some that have different skin colour, very different skin colour but they are still like us.
How are they governed?
Governments are much like ours, religious dominions, dictatorships, criminal organizations and normal democracies. They seem familiar, yet they are most different. Little trade between governments or systems. It is very hard to trust other systems. The universe is very brutal, it is not one big happy family.
Only one treaty exists, one Accord that seeks to control the chaos.
The Accord of Ramaln. Simple put it is the “Fair Warning” treaty.
I want to attack you. I must give you 90 solars warning. 90 of your days must pass . Why? Why would all the known space traveling species agree to this? Because, before this was chaos. I would secretly build up all my resources to attack you. I would succeed, but you would have an underground that would drive me from the planet. Both systems destroyed ruined. Then I would build up my forces and attack you! Who has the biggest army would win. Then my allies or your allies would come along kick your butt and destroy your worlds. You get the idea, my allies, your allies.
90 solars, 90 days, allows for all parties together who want to be involved. 90 days allows the aggressor to re-consider, for a negotiated peace or succession of hostilities.
What happens if you don’t warn your enemy? Your system becomes the “disease” that humans deal with. You are fair game for everyone else. For my allies to come and get you or ANYONE to come and get you.
If you found out a human was coming to deal with your transgression, you immediately sued for peace, for the end of agression. Such is the fear and force that humans bring to the universe.
