Forgive me Patrick if I find those a bit bland. They’re pretty typical RPG abilities.
How do you use Grief? Oh my. You use it for funeral rites. You use it to swear vengeance or enact revenge on your father’s murderer. You use it to forgive.
How do you use Tradition? To right fallen communities, to bring them from the path of the Shadow. To go before the king. To teach children, to impress foreigners, to be really conservative assholes. Why did Numenor fall? It broke with Tradition.
How do you use Family? To sire children, to convince your wife, to argue with your father, to put your upstart brother in his place.
Escaping, Climbing, Foraging and Hiding are obviously useful, but they are directly at odds with the expectation and needs of the Mouse Guard and the mouse communities. Obviously, the Tolkien stuff needs a slightly different premise, but it needs a strong one nonetheless.
