Month 1, year 1, unnamed tribe, unnamed vilage
You kneel down and look into the pool... and wait... You don't see any fish but you do remember sipping the water and it was fresh and suitable at the time. You bet it still is.
A month passes and the weather has begun to turn rainy and overcast. A fine alternative, everyone agrees. You people manage to get a rather large fire up and running with a firedrill they whipped up and some of the drier wood. The thrush gatherers do a mediocre job getting enough for a few small shelters and some small sticks and you begin on them immediately. The shelters are just big enough for a marathoner to sleep under, being raised thrush with two sticks over a dug in enclosure, acting like a small tent and shedding both rain and water.
People rejoice about the fire, sitting near it to warm their sinews and chat about the great things their tribe will accomplish. Apparently the excitement of such things hasn't worn off for some quite yet.
The thrush gatherers all agree that it would be easier to get building materials if they had tools built for such things like a crude axe, shovel, or hammer.
The gammas set to find the plants have some difficulty, but only because they do not know the area quite well. They figure if they knew a bit more about it they would have piles of the damn plants.
The food supply has gone from dwindling to alarming and rations will only last 2 more months without intervention you estimate.
What would you order next month?
