Different topic but since you mentioned it...
I didn't want to use the entire map just yet. You can see from the map I posted on the website that there is a significant section at the top that is not accessible. There's also two other continents and smaller islands that currently are not in use. Eventually I'll have a need for Armorica (France) and that'll open up. But, I'm a bit limited on how much of the world map I can use.
I wanted to take the focus of the novels and really delve into them. The goal is to basically set the players in the time period of the first novel (now) and then progress as the mod expands. The first novel focused on the Eastern Saxons, Northern British, and the Franks to the South (in Armorica).
But without getting into the mod too much here (which I'm trying to avoid right now until more of it is structured and completed), I wanted at least something on the map to appear as a boundary rather than the camera ending.
