The Faraway Paladin: Volume Three Primus
The Lord of the Rust Mountains

But order has not completely been restored to this faraway land; strange things are happening, starting with plants blooming out of season and dying at random. At Duke Ethel's request, Will and Menel are off to investigate, not knowing that their journey will lead them to an ominous prophecy and the Rust Mountains, the capital of the dwarves.
