"Popkill" – population killing – is a property of some nations' dominion. Any province under their dominion will lose population each turn; this effect severely reduces their income over time.

Since they have little gold, their dominion also freespawns troops for them to use in their own provinces with their dominion. Since they don't participate in the usual gold economy, these nations play very differently than normal.

These nations are:

• EA Therodos, an underwater nation of unquiet ghosts
• MA Ermor], a post-apocalyptic nation of Roman-style undead * [[asphodel-ma|MA Asphodel, a nation of undead dryads and vine-animated animal corpses
• [[r'lyeh-la|LA R'lyeh], a nation of underwater abominations spurred on by dreams of madness
• [[lemuria-la|LA Lemuria], a nation of Roman-style spectres

Generally, these nations will dump their income scales in pretender creation; MA Ermor will generally take Turmoil 3, Sloth 3, Death 3, and Heat/Cold 3, since it is futile trying to get income out of provinces with their dominion, and they have no national recruits anyway.

MA Asphodel and LA R'lyeh sometimes attempt to preserve population by taking a starting dominion strength of 1, so they only have at most one dominion candle in each of their provinces. This results in a much gentler population die-off, allowing them more gold for longer.
