Edward's sword that Bella has crafted I pictured as something like this:

Except that it is much longer and there are two dragons that make up the grip instead of one. But the craftsmanship is essentially very similar.

In chapter 23 I brought up the term "grub house." It's a relatively new archaeological term derived from the German 'grubenhaus' meaning Pit Structure. It's a very common Anglo-saxon building used typically for one family to share.
Here is an excellent site that describes how they were constructed.

Map of Britain's Anglo-Saxon Kingdoms

Here is the map of Britain from The Age of Darkness. It's semi-accurate - these tribes were roughly in those places. But Cornwall was actually significantly smaller while Wessex reached further to the East and Sussex is usually known to stretch along further across the south.

All the important places are indicated on the map. There were others mentioned but to be honest they're not really crucial to the story.
