Writing has been slow this month, but I finally finished Chapter 7 a few days ago, and after spending more time researching, map reading, and generally fiddling with the planned order of the next few chapters, I finally started Chapter 8 yesterday. This takes Gwernin and his friends to Aquae Sulis (Bath). It seems pretty clear that a lot of that Roman city was in ruins by our story date of 562 AD, but the hot springs were still there... and perhaps other interesting things.
Some nice cool damp weather here in Denver today, which matches the weather I'm describing in the story for a change. :)
