How does that affect the risk of inbreeding?
It removes it entirely. In other words, although it makes it difficult to diagram nice, clean family trees, having a norn breed with one of its family members won’t increase the risk of harmful mutations and other problems, as it might in most real life species. It may tend to reduce the variation in the overall gene pool over time, but that can be alleviated by occasionally introducing new norns into your Albia.
