Racial Composition: If a player decides to add a race with an ecl of +1 or higher in their kingdoms population subract 20% from the total population for each ecl over 1.
For eample if a player wanted to include a community of drow their ecl would detract 80% from the total population.
The player can then assume the drow could represent up to 20% of their total population to keep things balanced.
It could be useful for quick and dirty kingdom/area gen, either for players, or GM. There are larger and more involved ones, with interaction and all that, but this is fast, linear and all on one page. Nice, thanks for sharing!
