This is my view of a poem for The Hobbit by JRR Tolkien. Just how Aragorn proved who he was with a poem, except this is for the dwarves, Gandalf, and Bilbo.
Let them be loyal
let them have faith
their feet find a path
in light and in darkness.
The moon light the way
the sun make a trail
dependable as the Earth
for all of their days.
