It has been two months since the attack and our group has atrophied to eight. Four disappeared one night while the rest of us slept. Each of them had argued with us that week about returning to the base to see if they could reopen the portal, so I can only hope they left in the night to go back without us. Three we lost to thirst, hunger and the elements. I am ashamed to notice that our smaller group is now more manageable - finding food and water is easier with fewer mouths to feed.
During this time, the invaders have not been idle. Yesterday we stumbled upon what seems to be some kind of transport route, moving resources they're mining to supply their forces. The lanes sprawl out across the land like a spider web, with all the grace and aesthetics of Forerunner design.
We rested and argued for a while about which direction to head in. There was a real danger we could accidentally stumble upon an enemy base, but that could also lead to supplies, perhaps even a vehicle we could steal.
We are hungry and exhausted and cannot last much longer in the wild. One of us, Brewer, said as much and not for the first time raved about surrendering. We thought we had talked him out of it but the next morning he had gone. If he had successfully surrendered he could have given away our position, so we had no choice but to start moving immediately.
We look for cover but avoid the trees because I have seen strange shimmers and movement amongst them. I am scared and tired and want to give up. But that won't get me back to you.
