Colony: Hire a lumberjack, preferably a singing Brit.
Action: Quest, study the fauna. Hopefully I can find something easy to hunt, to make fur clothing to stay warm.
Diplomacy: Will trade 5 wood for food.
Name my colony "Truthville" with the motto, "Make the Empire Great Again."
Question:
If the worker is a permanent purchase, does that mean I cannot have more workers unless I increase delegation? Or will I be able to hire an additional worker next week, if I keep my delegation the same?
That is indeed correct, if your delegation keeps on being 50 SP, you have to fire a worker to get a new one.
