Jeff shared some insights on Boldhome on FB - cross-posting for those not on it. The map is wonderful!
Boldhome is the largest settlement in Sartar, comparable in size to all of the other cities of Sartar put together. It is the religious, political, commercial, and cultural center of the kingdom - the center of the Orlanth Rex cult, and so much more.
It is also physically BIG. Check out how big it is by seeing how much space it occupies in the Quivin Mountains. And imagine it surrounded by high snow-capped peaks.
But there is also so much right around Boldhome. The strange dragonewt city of High Wyrm. The terror birds of Bird Site. The gorge of Enothea's Cut. The mountain refuge of the Broadview Inn. Not to mention the amazing stone road that cuts right through the Quivin Mountains, with the stone Geo's Ridge Inn as a refuge and hospice.
One might even think that it would make a perfect home base for a Sartar campaign!
