The Return of the Dwarves Book 1

Hundreds of cycles have passed in Girdlegard since Tungdil Goldhand vanished. The dwarf Goïmron works as a gem carver in the city of Mallenias Watch. He is particularly fascinated by the old times, the great times of the five dwarf tribes, and so spends his spare time searching the markets for records and artefacts for clues about their proud history. And then Goïmron comes across an extraordinary book.
The wealth of detail it contains leaves no doubt that the book must have been written by the heroic Tungdil Goldhand himself. But, impossibly, the last entry seems to be recent.
