I have been playing on scattered maps, and tons of Fomorians, every sea area has a fortress and piles of roving Fomorian ships make life miserable, in a good way.

I am now playing on a 6-8 continent map, and the only other parameters I changed were land to 80% (from the 40% of scattered) and no world wrap. There are still plenty of sea areas, but no Fomorian installations or roving ships except for one fortress up in a corner of the map.

All maps have been huge in size.

Obviously more land means less sea, but why no Fomorians in the sea areas? Which advanced setting nuked them, land mass or no wrap?
