GAZ10 Continental Humanoid Migrations, 24 miles per hex

GAZ10 included two migration maps on its poster map: Tribal Migrations, showing the whole of Brun; and this map of the Known World area. Together they form a detailed picture of the history outlined in GAZ10’s text.

The map itself was a standard Known World 24 mile hex map, with just the base terrain and water feature layers. The map did not add settlements or other icons, but it did provide the intriguing possibility of ruins and other remains left behind by the migrations.
