Welcome to "Port Royal" RustyNell, my girl!
Jump in with both feet and don't be shy. This is why this thread was created. It is to help those with questions about time, placement, position and direction. Ask away.
Now, even though you are a 'pub owner' - I think you would be also busy about town purchasing rum, ale, beer and other items for your establishment. So, you would be out and about. You would deal with the locals; such as merchants, vendors and do not forget...the shady side of the business. You are a source of news...and gossip. If you had your fingers into shady trades/deals...you'd probably know what and who was doing what in your backyard.
So, read up on the storyline (gosh, do you have time?) and then jump on in and play!
Again, we happy to have ya...
