They washed their hooves in the waters of the icy river, gently lifting their heads to enjoy the red nuts on the trees, and chew on the leaves of the Scotch broom.

That was a lovely time of year. Standing on the watchtower built alongside the wall, I waited for the instrument—fashioned from a unicorn horn—to blow at twilight. Moments before the sun set the horn would sound—one long note, followed by three short ones.
