Håvard’s Laterre

Håvard whipped up this map amid discussions of Laterre, the origin world of the people of New Averoigne in Glantri. He wrote at The Piazza at the time:

Here’s a totally non-canonical map of LaTerre. I actually made this many years ago, but updated it a bit today.

And he didn’t stop at including Old Averoigne, nor indeed Caledonia, home of the people of Klantyre. He also added various other Earth-themed crossover references, including the AD&D Historical Resource series, as well as links to Scandinavia based on GAZ7, and other minor references.

The exact nature and status of Laterre and the Dimension of Myth has always been rather up in the air, and even as recently as 2025 there have been in-depth discussions about it at The Piazza. Thus far, this is the only map of the world of Laterre as a whole; there is also X2’s Province of Averoigne map detailing that small province, but nothing else.
