I suggest making a elder scrolls morrowwind map of the island Vardenfail (probly spelled wrong).
If u look at the map (ull have to go online to see it)
But there a Red Mountain in the dead center with what could be a good sized territory with 3 or 4 regions with only one entrance to get in it bc its completely surrounded by a magical fence. But also the is a underground attack from outside the fence u can make on red mountain
There's a place on the south of the map called Vivic that is 9 or 10 cantons. Could make a pretty good bonus
Same with a group of islands to the east and north east of the map would make good bonuses
And randon citys through out the rest of the map
Look it up. Check it out. Let me no what you guys think.
