Elder (Ruis)

Elder closes the tree-calendar year, and Celtic tradition treated it with real caution — associated with the Cailleach, the crone-goddess of winter and old age, and with a folk taboo against burning its wood carelessly. It's simultaneously a healing plant and one that demanded respect: endings, in this tradition, are never treated casually.

As a tree sign, your theme is closing chapters honestly rather than letting them fade out unfinished — you tend to be the one who says the hard true thing that lets a situation actually end. The wisdom you carry was earned through real endings, and it's worth more to the people around you than they usually realize until they need it.
