Hagalaz is the rune of destruction. Its name literally means "hail", a potentially very destructive phenomon. Oddly, there is also a connection to the idea of a windfall. Hail comes from storms which can knock fruit from trees (making it easier to get) or beach whales for easy capture. Much of the end result of this rune comes from perspective. While destruction can be harmful, it also clears the way for new growth.
Divinitorily, it represents loss, destruction, clearing, or testing. Used magically, it removes unwanted influences and breaks destructive patterns.
