Skrog cares nothing for people, and refuses to participate in the rites of guarding. God sends a series of visions to terrorize Skrog, but instead of knuckling down, Skrog becomes ever more adamantly opposed to God and God's will. His example is so ferocious that the community rallies around Skrog, and in the end, they sacrifice all the newborns, in a massive blood ritual.
In which the Tsalal have... interesting ideas of what counts as acceptable children's entertainment (not that the children themselves agree with these choices— for all the wrong reasons):
Oh I hate [the Tsalal adaptation of The 120 Days of Sodom]. Festival time when we were kids, we'd get dragged out to watch it, every single year. Yes, yes, yes, beloved children's classic the whole wide world over. But damn god, there's no plot to it, no story, it just goes on and on and on.
The Yag, the Kings in Yellow and how the Hali treat torture. Everything about the Tsalal.
The Tsalal have their own brand of Nightmare Fuel, the "Nameless Glacier" in the center of Antarctica. And the culture of the so-called Cold Islanders.
One of the large carnivores living in Antarctica is the Antarctic Teratorn, a Giant Flyer vastly larger than any other flying bird in the world. Normally it scavenges off the frozen bodies of large animals, but in summer it has to hunt. It does this by harrying its victims and spraying them with stomach acid until they collapse from exhaustion, at which point it devours them alive. One story follows a European explorer who meets this exact fate; he is ripped open and devoured, his bones broken and his flesh torn off in strips, and yet he remains alive for some time after it starts eating.
