There are a LOT of things about the Lore of Nott that are interesting and possibly even eye-opening. But to me, one of the MOST important things to note is that the Norse have an actual BLACK GODDESS. Given the amount of racism present in the modern Heathen movement, I feel like this is something we should be screaming from every possible platform at those who would drag our traditions through their white supremacist white-washing.
Hagalaz means there will be change. Hard change. Probably painful change. But it also contains within itself the grain. The new beginning. The seed for what is to grow in the now barren waste. The faster the change, the sooner you can find yourself planing something even better in that space.
