From publisher blurb:
The Age of Hammerfall has reached its end, the great glaciers of the Winter of Discontent are finally receding. Into the lands of the thaw go the wyrman survivors of a 9000 year exile, there to settle new lands and new civilizations.
The Age of Thaw is the quintessential guide to the realm of Ereth and the world of Yarnia within the modern age of the wyrmen. An unmissable companion title to the other Wyrd core rulebooks and guides, the Age of Thaw features more than thirty highly detailed, photo-realistic maps, including maps of the entire world of Yarnia and all the major cities of the setting. Cities include keys with illustrations of all major landmarks.
