There are plenty of spots open for antagonist types. There could be Ostartian (colonists) that want to rid the Earth of the Artifaces and the Therianths and reclaim what was once their peoples home. There with the reverse where the magic peoples and shifters want to be rid of every last colonist. There are magic people or shifters that want to ignite wars of their own between each other. There will plenty of bad blood, old wounds, and fresher cuts to pick at.
I'm planning on being an "antagonist" type. Someone who's actively working against these strangers from off world. If that's a viable plot.
I think right now we are focusing 'on planet'. We may be bringing in off planet antagonists as the game progresses but we need actual characters to populate the earth first.
I ope that makes sense and I didn't mess anything up. 2am is not nice to me. Night Lovelies.
