Crosses the Line Twice: The Tsalal's gruesome brutality frequently goes so over-the-top that it loops around to becoming hilarious. Of particular note is the mock "Ask Me Anything" session with a Tsalal poster, who regards the nightmarish horror of the culture around him as normal, if slightly embarrassing. The Tsalal poster is inordinately proud of himself for convincing restaurants to stop selling the meat of Irish slaves, and while he says that he has never seen The Human Centipede, he claims to have met one once.
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.
The Cold Islanders are so evil and depraved that even other Tsalal fear and hate them, considering them inhuman. The Cold Islanders believe that everything is exactly the sum of its parts. This philosphy leads to exceedingly brutal treatment of slaves, who are seen as no more than resources. It also advances the baffling idea that since humans are no more than the sum of their parts, it should therefore be possible to cut someone into pieces, put them back together, and get a living human. Obviously this never worked, but they tried it out on a lot of people. While they never succeeded in making a true "Remade Man," they did make mutilated faux-Remade Men who have grafted body parts from other people and were tortured into believing they were "remade" in this way.
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.
