Looking at the Basic data:
Ok since the data is broken down into two parts lets look at them seperately.
Drethen
The population of the cattle clans is up, and the number of cattle is WAY up. We've got a new mechanic showing this turn though, a point reserve. Drethnor has agreed to spend two points every turn to enforce certain rulings. He may not get any benefit from this during a turn, or he may get a lot, but no matter what he pays turn after turn before he can take any other action.
We also see a marked increase over last turn in both faith and fear points. Last turn they were gaining 11 faith and 10 fear, 21 points total, this turn the drethen are providing 15 points of each! Why? Before the tribe had NO formalized method of worship or rights that would lead to them thinking consiously about Drehnor's might. Now they have a sacrifice, it's minor but it keeps the great god in their minds, they also have a penalty for missing the sacrifice or stealing drethnor's meat; and they have SEEN what happens when someone angers their god. That lead to a good jump in both faith and fear. The organized ritual and punishment can be thought of as a form of propaganda, it keeps the people thinking of Drethnor and constantly reminds them that he COULD strike them down if he so chose.
The Chosen
The numbers are up here but not by as quite as much. The chosen are breeding slowly compared to the humans, part of it is that they still have a smaller base population, and part of it is because 10% of their children are giant intelligent STERILE birds. That's a 10% decrease in population every turn when your looking at numbers for breeding.
The total power of the god (faith + fear) hasn't increased more than a point this turn. However some change has happened. Last turn the Chosen provided Drethnor with 10 faith and 5 fear; this turn the faith has gone up and the fear down. The split is 12 faith and 3 fear.
Part of the reason the power level is so low is that the population is low, there aren't a lot of vulture men or Drethnor's own sitting around thinking and believing. However the real change comes from their "blessed" status. They don't fear Drethnor as much and they have a bit more confidence that come what may he will take care of them and lead them towards greatness.
