This scenario is set in Britannia in 84 AD. You will face a mild military annoyance from the Picts. Resources are somewhat scarce and you will need to set up a number of trade routes to supply your populace and generate a decent income.
A little bit of trivia:
Coria (modern day Corbridge/Corchester) was a Roman Town founded in 84 AD. It acted a supply town for the local wars against the Celtic tribes (mainly the Picts) in modern day Scotland. It was abandoned about 40-50 years later.
Quick disclaimer: I did my best to create a somewhat customised map, but the editor is a huge pain in the ass, it started crashing as soon as I used the paint ground feature for more than a second.
