As I near the end of Wind and Truth, Brandon Sanderson's 1344-page final book in the first half of his epic Stormlight Archive fantasy series, I am reminded of the following quotation from J. R. R. Tolkien. It is part of The Homecoming of Beorhtnoth Beorhthelm's Son, a play based on a fragment of a poem about a historical battle between the English and Viking invaders.
This is not pessimism, but a call for strength and courage during dark times, which come to all.
Heart shall be bolder, harder be purpose,
More proud the spirit as our power lessens!
Mind shall not falter nor mood waver,
Though doom shall come and dark conquer.
