Three years of peace in her little slice of heaven. A slice of heaven carved out in hell.
You were always aware that your life in the beautiful canadian woods was not the world that others lived in so far, yet so close by. Transportation isolation made it difficult to find you, and your cabin was nestled beneath trees cover such that Advent flyovers, such as they were, would never spot you unless they flew directly over your spot.
Even this far away though, the presence of advent was felt in small ways. The animals to be hunted started disappearing, or at least specific species disappeared. First were the wild wolves of the forests when you were still a child, then the few wild stallions that trotted around in your early teens. Their presence was missed, not because it deprived you of food variety, but because they added some indication that life was still going on as normal. Then a sort of apocalpyse happened, and dozens of species just disappeared. Bears, moose, bison, all manner of mammals all disappeared within the past few years, suddenly and without trace. Poulty and fish were still available to hunt, and it became more difficult for you to realize that things were really still the same.
That little bubble of idyll died a night ago when you heard an explosion, and you stepped outside to see an Advent UFO falling out of the sky. It crashed barely three kilometers from you, smashing into a small hill then sliding down to knock away several dozen meters worth of trees before it lost so much momentum. After that, you could hear the familiar sound of heavy plasma fire as bright green flashes showed the advent burning away the surrounding forest, readying the land to allow a team to extract them in the morning.
What then surprised you was when the sound of conflict started again, a few hours later. The familiar crack of automatic fire - M4A1 rifles - in the air, while orange fire lighted up the morning forests. Someone was fighting the aliens nearby, bringing the fight to you!
