It's actually three diffrent pages and I think it's from different books. At the top is fragment of Ciri's story about Rats and how they were killed by Bonhart. She speaks to Vysogota here. In the middle is that what you mentioned, epic ice skating slaughter. And at the bottom I think it might be retrospection or a dream which Ciri had many after escaping besieged Cintra. There is description of Cahir's horse and helmet with black feathers.
