a long time ago an alien species crafted a interstellar space cannon that could fire projectiles containing entire communities of it’s people across the galaxy in hopes of finding place where they could settle and thrive.
one of those projectiles would arrive on earth and after the impact a vast community of the alien species would set out in search of food and a good environment within which they could survive.
those species are now commonly known as ticks and as they have discovered that we are at war with them they are using biological warfare themselves to keep us within our cities and away from them and the hosts that they live off of in the wild. they have a happy existence feeding off the blood of animals and they will not tolerate our chemicals and concrete.
it is an ugly war, we cannot intercept their strategic plans or use our spy technologies to track them. we cannot use economic power to turn their own species against themselves or easily manipulate their supply chain without hurting ourselves more. what is more, their attacks on us are done with ghost like stealth with a time delay that leaves us guessing at where the attack occurred. we are left wondering if they have leadership or is every last one of them a trained attack weapon with the knowledge to survive alone or in community with little more than a blade of grass until their next unsuspecting supply of goods comes by.
So, what do we do?
