We started with Milyagon, a rural village that used to be a military fort. I drew a map for the fort and the town. Wilken Woods is on the map and it became a magic forest across the river from Milyagon. Now through the woods and across another river and we're adventuring in Tobbins Shire. So definitely bottom up for our world building. And I just build as we play.

That's a much more manageable way to do it.

I didn't really have a plan. It just grew.

Which is not always the best way to do things but it worked for me this time.
